与PI控制器相比具有较快的响应速度、较小的超调和较强的抗干扰能力。
标准的自抗扰控制器不需要知道对象的精确模型,只要知道了模型的阶次就可以设计出对象的自抗扰控制器。
但在有些复杂的应用场合,完全不利用被控对象模型进行系统设计,往往难以充分发挥出自抗扰控制方法的优点。
在PMSM调速系统中需要设计速度环的一阶自抗扰控制器[1-2],若负载扰动较大,ESO则难以保证较高的估计精度,导致自抗扰控制器对扰动难以进行很好的补偿。

Firstly, an adaptive disturbance observer was designed by the prediction error. For the internal and ex-ternal uncertain disturbances suffered by the system, the disturbance observer estimated the total disturbance and made compensation in the form of current. Moreover, the transient process and steady-state process of the system were consi-dered separately, and a new loss function with dynamic weight factors was designed. The MATLAB/SIMULINK simula-tion showed that, compared with the traditional control method, the method proposed could maintain high-speed dynamic response in transient state and low current ripple in steady state, and show excellent performance in coping with parameter mismatch and load mutation. It has better steady-state performance and anti-interference ability. The method proposed can effectively improve the dynamic performance and robustness of the system, making the improved system more suitable for the application scenarios of packaging machines.KEY WORDS: permanent magnet synchronous motor; adaptive method; disturbance observer; dynamic weighting factor未来五年是全面建设社会主义现代化国家开局起步的关键时期,包装印刷业也正在走向高质量发展的重要转型阶段。

现阶段,国内急需解决的主要问题就是控制器的国产化,如何研究并制造高性能、高可靠性的伺服系统有着重要的现实意义。
目前,永磁同步电机的控制方法主要有两种:矢量控制方法(VC)和直接转矩控制方法(DTC)。
矢量控制方法出现较早,技术比较成熟,其优点在于利用高性能的DSP和高精度的光电码盘转速传感器,调速范围可达1:1000,同时系统的动态性能也很好,是目前最常用的控制方法。
但它存在(1)计算复杂,需要作静止、旋转坐标变换,影响实时性;(2)转子磁场空间位置难精确定位,影响旋转坐标轴线定位及解耦效果等不足,由此造成实际系统的实现效果很难达到理论水平。
相比较矢量控制方法,直接转矩控制摒弃了解耦的思想,取消了旋转坐标变换,简单的通过电机定子电压和电流,借助瞬间空间矢量理论计算电机的磁链和转矩,并根据与给定值比较所得差值,实现磁链和转矩的直接控制。
于自抗扰技术的PMSM交流调速系统的研究

研究与设计Research and Design52 引言永磁同步电机在各类电机中,具有效率高、体积小、温升低、无需励磁绕组等诸多优点。
随着永磁同步电机在各种不同场合的应用日益广泛,其控制理论也不断成熟,先后形成了三种控制策略,分别为:恒压频比控制(VVVF )、磁场定向控制 (FOC-SVPWM )、直接转矩控制(DTC )[2]。
随着控制理论的不断发展,出现了以系统状态方程为研究对象的现代控制理论,在交流电机控制系统的研究中引进了诸多先进的控制策略,例如神经网络控制、自适应控制、模糊控制等,并且取得了一定的成果。
但现代控制算法往往计算复杂,对被控对象地精确数学模型依赖较强,难以应用到实际工程[4]。
ADRC 是一种新型的非线性控制器,综合了经典PID 控制器不依赖于被控对象具体数学模型的优点以及现代控制理论的设计方法[3]。
1 PMSM 数学模型介绍为实现PMSM 定子电流解耦控制,往往在交直轴坐标系下分析其数学模型,文献[4]指出,根据定子电压方程、磁链方程、电磁转矩方程以及机械运动方程,在i d =0 控制策略下,速度环以i q 作为对象输入,w r 为输出,可得如下微分方程:w J p i J p T J w R r n f q n l 2}=--X o (1.1)式中,p n 为极对数,J 为转动惯量,Ψf 为转子磁链,i q 为q 轴电流,T l 为负载转矩,w 为电角速度,R Ω为阻尼系数。
电流环以[u d u q ]T 作为输入, [i d i q ]T 为输出在dp 轴下可如下得微分方程: (1.2)()i i L R i i wi w i L L u u 1Wd qa a dq qd af a d q }=-+-+++o o ==>=G G H G 式中, L d =L q =L a 为交直轴电感,R a 为定子绕组,W 为系统未知扰动。
2 自抗扰控制器自抗扰控制技术是一种典型的基于误差来消除误差的控制策略,其最突出的特点就是把作用于被控对象的所有不确定因素都归结于未知扰动,然后用被控对象的输入、输出数据作为控制器输入,经过一系列运算处理,对此扰动进行在线估计与补偿。
基于自抗扰理论的PMSM电流环控制算法

基于自抗扰理论的PMSM电流环控制算法王福欣;郜世杰【摘要】针对传统的永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)采用比例-积分-微分(Proportion-Integral-Derivative,PID)控制器进行电流控制,在恶劣环境下电流波动较大、稳定性较差的问题,提出一种基于自抗扰理论的PMSM电流环控制算法.采用自抗扰控制器(Active Disturbances Rejection Controller,ADRC)取代PMSM q轴电流环的PID控制器,并在MATLAB/Simulink中搭建ADRC模型,进行建模仿真.结果表明,将自抗扰理论应用到PMSM电流环的控制算法中,PMSM的电流波动更小,运行更平稳.【期刊名称】《上海船舶运输科学研究所学报》【年(卷),期】2018(041)003【总页数】5页(P24-28)【关键词】永磁同步电机;PID控制器;自抗扰控制器;电流环控制【作者】王福欣;郜世杰【作者单位】上海船舶运输科学研究所航运技术与安全国家重点实验室,上海200135;海军驻广州地区军事局,广州510000【正文语种】中文【中图分类】U664.1210 引言永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)伺服控制系统一般采用三闭环结构(即速度环、位置环和电流环),其中电流环作为最内环结构,用来保证定子电流对电流指令的快速准确跟踪,其控制性能直接影响着位置环和速度环的控制性能,对于整个电机的控制而言具有重要作用。
目前在PMSM的磁场定向控制中,通常采用比例-积分-微分(Proportion-Integral-Derivative,PID)控制器分别对旋转坐标系的d轴和q轴进行控制,控制过程简单,容易得到实践[1]。
随着电路电子技术的发展,PID控制器在控制电流方面逐渐暴露出电流波动性较大、抵抗扰动的能力较差和稳定性不足等问题。

So it has been widely used in important fields, such as transportation, military, industrial, medical and aviation[1,2]. The control methods of high performance PMSM system consist of vector control (VC)[3], direct torque control (DTC)[4,5] and model predictive control[6,7]. In recent years, a kind of optimization control method finite control set-mode predictive control (FCS-MPC) has been paid wide attention. FCS-MPC can be divided into current prediction control and torque prediction control[8,11] according to the control target[9,10,12].In traditional torque prediction control, it is necessary to adjust the weightcoefficient to ensure that the system has good dynamic performance, duing to the inconsistency between the stator flux and the electromagnetic torque[13]. In contrast, current prediction control has the same magnitude with the current variable, which can avoid to design weight coefficient. The traditional FCS-MPC needs to predict current values corresponding to all the basic voltage vectors in each sampling period, which makes it have heavy computing in the actual industrial control[14]. Zhang Y C[10] proposes a fast vector selection based on FCS-MPC, which reduces the complexity of computation and algorithm. As the back electromotive force (EMF) is DC amount, the method that estimates the back EMF of the current moment by calculating the values of the first three moments and averaging them will increase system complexity. Meanwhile, external interference will lead to estimation error. In this paper, the extended state observer (ESO) is applied to observe the back EMF in real time, and a new FCS-MPC strategy is constructed to improve the control performance of the system.FCS-MPC speed control system of PMSM requires accurate rotational speed information. The speed sensor with higher accuracy and resolution is expensive, and there are problems such as complexity of the system, noise quantization and so on. Therefore, the study of speed sensorless has drawn great attention. At present, the speed control methods of the motor system consist of high frequency injection (HFI)[15], extended kalman filter method (EKF)[16], model reference adaptive control (MRAS)[17], sliding mode (SM) variable structure[18] and extended state observer (ESO)[19].The arc-hyperbolic sine function of many speed identification methods can make ESO have a good estimation effect, and the ESO based on the arc-hyperbolic sine function, which does not need accurate mathematical model, has strong anti-jamming capacity and rapid convergency and so on. Speed regulator in FCS-MPC system of PMSM usually adopts PI algorithm. The control effect can be obtained by adjusting the PI parameters at different speeds and external disturbances. In order to improve the robustness of the system speed regulator, the authors proposed a new anti-disturbance rejection control strategy based on the arc-hyperbolic sine function[19-21] in recent years which has drawn wide concern. In the Ref.[20], the tracking differentiator of the arc-hyperbolic sine function is presented, in which the ideal differential signal can be obtained, and track response speed is quickly and stably. In Ref.[19], an extended state observer based on the arc-hyperbolic sine function is put forward. The observer can accurately observe the disturbance variable, and the response speed of the system is fast and stable. At the same time, the initial parameters of ESO can be used to suppress the differential amplitude. Active disturbance rejection control (ADRC), which does not require accurate mathematical models, has strong robustness and immunity. Therefore, ADRC based on arc-hyperbolic sine function is used as the speed regulator in this paper.In order to improve the control precision, robustness and control performance of the system, the ADRC FCS-MPC strategy based on ESO is proposed for PMSM system, which can reduce the cost of sensor at thesame time.1 Mathematical model of PMSMIn this paper, taking the surface mounted PMSM system as the control object, that is Ld=Lq=L, so the mathematical model in the synchronous rotating reference frame is(1)where id, iq and ud, uq are d, q axis currents and voltages of stators; Rs is stator resistor; Ls is stator inductance; ed, eq is back EMF; ωr is rotor velocity; ωe is electrical angular velocity; P is pole pairs; ψf is rotor permanent magnetic flux; TL is load torque; J is moment of inertia; and B is coefficient of friction factor.2 ADRC FCS-MPC strategy of PMSM system based on ESOFor the three-phase PMSM system, the system block diagram of active-disturbance rejection FCS-MPC based on ESO is shown in Fig.1.Fig.1 System block diagram of active disturbance rejection FCS-MPC strategy based on ESO2.1 Design of speed observer based on ESOAccording to the principle of stator current state Eq.(1) of PMSM and ESO, the first order state space equation of the system is constructed as(2)wherev1=[id iq],u=[ud uq],h=[-ed/L -eq/L],And h in Eq.(2) is extended to the new state variable v2, where q is present, and q(t) is bounded. The extended equation of Eq.(2) is(3)Eq.(3) is observable, and the second-order ESO of Eq.(3) can be constructed as(4)where β1>0, β2>0, β3>0, and arsh(·) is a smooth continuous nonlinear function.In the second-order ESO of Eq.(4), there are(5)where are the estimated values of id, iq; are the estimated values of counter electromotive items.The observed value of ESO contains the information of speed, i.e.,(6)where are the estimated values of ψd, ψq. The estimated value and position can be obtained as(7)2.2 Design of active disturbance rejection speed regulator based on arc-hyperbolic sine functionADRC consists of first-order tracking differentiator (TD), ESO and state error feedback control law. The speed tracking error can be reduced through the first step tracking differential. The system state and perturbation can be estimated by ESO in real time. The disturbance can be compensated by means of the state error feedback control law according to the separation principle. The structure is shown in Fig.2.Fig.2 Speed controller based on ADRC of PMSM system2.2.1 Design of first order tracking differentiatorA differential equation of first order speed tracking is constructed by using arsh(·)[20] as(8)where ωm is speed setpoint value, w is the transition variable, parameters b1>0, a1>0. a1 is close to 1 in usual. The appropriate increase of b1 can increase the response speed and reduce the tracking error. The idealresponse output of ωm can be obtained by Eq.(8).2.2.2 Design of second-order ESOLetx1=ωr, y2=x1.(9)According to the speed differential equation constructed by Eq.(1), the first order state space equation is constructed as(10)where b0=1.5ψfP/J, y2 is the input of speed controller, iq is the output of speed controller.From Eq.(10), we can see that the load torque and viscous friction coefficient are changing interference signals. The various unknown disturbances are denoted by f(t) asf(t)=-Bωr/J-TL/J.(11)Let x2(t)=f(x1), and x2(t) is extended variable, that is The first order system constructed by Eq.(10) is extended to(12)The second-order extended state observer of the structural system constructed by Eq.(12) is(13)where b2>0, b3>0, a2>0. a2 is close to 1 in usual. The astringency of ESO is easy to be influenced by parameter b2. The extended state observer constructed by Eq.(13) can achieve accurate state variable estimation of the expansion Eq.(12) only when b2-b3a2>0, that is z1(t)→x1(t), z2(t)→x2(t).2.2.3 First-order active-disturbance rejection controllerThe error feedback control rate u0(t) shown in Fig.2 is used to feed forward the interference signal. It is designed as(14)where parameters b4>0, a3>0. a3 is close to 1 in usual. A small ripple of control quantity u can be got by selecting the proper value of b4.2.3 FCS-MPC based on fast vector selectionAccording to Eqs.(1) and (6), the current space state vector differential equation under the selected rotation coordinate axis is constructed asis=(us-Rsis)/Ls-z2,(15)where is=[id iq] is current vector; us=[ud uq] is voltage vector.2.3.1 Current model predictive control based on fast vector selectionThe traditional FCS-MPC calculates the predicted current for each fundamental voltage vector in the rotating coordinate system first, andthen calculates the corresponding minimum objective function value based on the predicted current, finally selects the voltage vector of the minimum objective function as the best output of the inverter. But it needs to forecast current for 7 times, which makes the amount of calculation relatively large. In order to obtain better control effect, the FCS-MPC strategy based on fast vector selection is presented in Ref.[10], in which the optimal voltage vector is obtained fast by summing the average to estimate the back EMF. Therefore, complexity of the algorithm and the computation is obviously reduced. However, the estimation of back EMF will increase the complexity of the computation and system, and external interference will lead to estimation error. In this paper, the Eq.(5) is used to estimate the back EMF.In this paper, the second-order Eulerian discretization method is applied to further simplify the Eq.(10)[10], that is(16)whereIn Eq.(16), the ideal voltage vector is obtained when i.e.,(17)Let uk(k=1,2,…,6) be the the base voltage vector of 6 sectors, and as longas the amplitude of the error vector is the smallest, i.e.,(18)When the output basic voltage vector is zero vector, the amplitude of the error vector is(19)The method can be summarized as follows: (1) is calculated by Eq.(17). (2) Judging the sector k (k=1,2,…,6) that located by Eq.(18). (3) Comparing e0 with euk by Eqs.(18) and (19). If e0>euk, the best voltage vector is euk, otherwise, the best voltage vector is e0.2.3.2 Control of delay compensationThe actual output voltage of the controller lags the current change in the actual digital system control[22]. To eliminate the negative effect of the system control performance by the delay, is calculated according to Eq.(36) in Ref.[14], and then the voltage is compensated at k+1 by appling the second-order Euler discretization method, which compensates the delay of the system.(20)The flow diagram of FCS-MPC based on fast vector selection is shown in Fig.3 with considering the delay compensation.Fig.3 FCS-MPC flow chart based on fast vector selection3 Simulation analysisThe model of Fig.1 is structured and simulated in Matlab/Simulink environment. The simulation parameters of PMSM system are shown in Table 1. The sampling period of the system is 10 μs. In o rder to verify the correctness and validity of the active-disturbing FCS-MPC method of PMSM system based on ESO, two FCS-MPC systems based on PI and ADRC are constructed by appling the same speed ESO parameters, and they are compared and analyzed.Table 1 Parameters of PMSMParameterSymbolDataStatorresistanceRs(Ω)3.45Windinginductanc eLs(H)0.012RatedpowerPN(kW)1.1FrictioncoefficientBm0.05PolepairP2 MomentofinertiaJ(kg·m2)0.00154RatedtorqueTN(N·m)3DCpowersupplyU dc(V)380RatedspeedωN(r/min)10003.1 Comparison of anti-load abilityAdjusting PI parameters to obtain the same transient of the two systems so that they can meet the rationality comparison. When simulation, the speed setpoint of PMSM system is 1 000 r/min, the PMSM system starts with load (1 N·m) and is loaded to the rated load (3 N·m) at 0.2 s. The response curves of two systems are shown in Figs.4 and 5, respectively. Fig.4 Dynamic response of speed sensorless PMSM system based on PI FCS-MPC strategySimulation analyses are as follows.1) ESO speed estimation. As can be seen from Figs.4 and 5(a) and (b), both the FCS-MPC PMSM systems based on PI and ADRC, the ESO speed estimates and the actual curves are almost coincident, and the speed errors are small, i.e., the speed observer can be quickly tracked and has a high recognition accuracy.2) Robustness of ative-disturbance FCS-MPC strategy for three-phase PMSM. Figs.4 and 5(a) show that the FCS-MPC PMSM system based on ADRC has smaller torque ripple and can be restored to the reference value, which means that it has a stronger anti-load capacity comparing with the FCS-MPC PMSM system based on PI. As can be seen from Figs.4 and 5(c), the FCS-MPC PMSM system based on PI has the smaller electromagnetic torque ripple compared to the FCS-MPC PMSM system based on ADRC. Fig.5 Dynamic response of PMSM system based on ADRC with FCS-MPC strategy3.2 Comparison of transient response characteristicsPI parameters are adjusted so that two FCS-MPC PMSM systems based on PI and ADRC have the same anti-load change capability as possible for which can meet the rationality comparison. When simulation, the speed setpoint of PMSM system is 1 000 r/min, the PMSM system start with load (1 N·m) and is loaded to the rated load (3 N·m) at 0.2 s. The response curves of two systems are shown in Figs.6 and 7, respectively.The following results can be obtained by simulation analysis.1) ESO speed estimation. As can be seen from Figs.6 and 7(a) and (b), boththe FCS-MPC PMSM systems based on PI and ADRC, the ESO speed estimates and the actual curves are almost coincident, and the speed errors are small, that is, the speed observer can be quickly tracked and has a high recognition accuracy.Fig.6 Dynamic response of FCS-MPC strategy on speed sensorless PMSM system based on PI2) Robustness of active-disturbance FCS-MPC strategy for three-phase PMSM. From Figs.6 and 7(a), the FCS-MPC PMSM system based on ADRC has smaller overshoot and shorter control period when the resistance to load change is consistent, and it has better speed transient response characteristics. As can be seen from Figs.6 and 7(c), the FCS-MPC PMSM system based on PI has the smaller electromagnetic torque ripple compared to the FCS-MPC PMSM system based on ADRC.Above all, the control method designed in this paper can guarantee the stable operation of the system when the load changes, and it can ensure the system has strong anti-load interference ability, low electromagnetic torque ripple, and good dynamic performance. It does better than PI control in the anti-load capacity and dynamic performance.Fig.7 Dynamic response of FCS-MPC strategy of speed sensorless PMSM system based on ADRC4 ConclusionIn this paper, an active-disturbance-rejection FCS-MPC strategy based on ESO speed sensorless of surface mounted PMSM was proposed. ESO based on arsh(·) is designed to estimate the speed and back EMF termaccurately. Compared with the PI-based FCS-MPC system, it can ensure that the system has strong anti-load interference ability, small electromagnetic torque ripple and good dynamic performance, which can achieve satisfactory torque and speed control effect.
