Closed-loop Control of DC Drivers直流驱动的闭环控制A basic scheme of the closed-loop speed control system employing current limit control, also known as parallel current control, is shown in Fig. 1-5B-1. ω* sets the speed reference. A signal proportional to the motor speed is obtained from the speed sensor. The speed sensor output is filtered to remove the AC ripple and compared with the speed reference.The speed error is processed through a speed controller. The output of the speed controller u c adjusts the rectifier firing angleαto make the actual speed close to the reference speed. The speed controller is usually a PI (proportional and integral) controller and serves three purposes—stabilizes the drive and adjusts the damping ratio at the desired value, makes the steady-state speed-error close to zero by integral action, and filters out noise again due to the integral action. The drive employs current limit control, the purpose of which is to prevent the current from exceeding safe values. As long as IA<Ix, where, Ix is the maximum permission value of IA, the current control loop does not affect the drive operation. If IA exceeds Ix, even by a small amount, a large output signal is produced by the threshold circuit, the current control, and the speed error iscorrected essential at a constant current equal to the maximum permission value.When the speed reaches close to the desired value, IA falls below IX, the current control goes out of action and speed controlled takes over. Thus in this scheme, at any given time the operation of the drive is mainly controlled either by the speed control loop or the current control loop, and hence it is also called parallel current control.Another scheme of closed-loop speed control is shown in Fig.1-5B-2. It employs an inner current control loop within an outer speed loop. The output of the current controller uc adjusts the converter firing angle such that the actual speed is brought to a value set by the speed commendωm*.Any positive speed error, cause by either an increase in the load torque, produces a higher current reference I a*. The motor accelerates due to an increase in I a, to correct the speed error and finally settles at a new I a* which makes the motor torque equal to the load torque and the speed error closed to zero.For any large positive speed error, the current limiter saturates and the current reference I a* is limited to a value I am*, and the drive current is not allowed to exceed the maximum permission value. The speed error is corrected at the maximum permissible armaturecurrent until the speed error becomes small and the current limiter comes out of saturation. Now the speed error is corrected with IA less than the permissible value.A negative speed error will set the current reference IA at a negative value. Since the motor current cannot reverse, a negative IA is of no use. It will however “charge” the PI controller. When the speed error becomes positive the “charged” PI controller will take a longer time to respond, causing unnecessary delay in the control action. The current limiter is therefore arranged to set a zero-current reference for negative speed errors.Since the speed control loop and the current control loop are in cascade, the inner current control is also known as cascade control. It is also called current guided control. It is more commonly used than the current-limit control because of the following advantages: 1.It provides faster response to any supply voltage disturbance.This can be explain by considering the response of two drives toa decrease in the supply voltage. A decrease in the supplyvoltage reduces the motor current and torque. In the current-limit control, the speed falls because the motor torque is less than the load torque that has not changed. The resulting speed error is brought to the original value by setting the rectifier firing angle at a lower value. In the case of inner currentcontrol, the decrease in motor current, due to the decrease in the supply voltage, produces a current error which changes the rectifier firing angle to bring the armature current back to the original value. The transient response is now governed by the electrical time constant of the motor. Since the electrical time constant of a drive is much smaller compared to the mechanical time constant, the inner current control provides a faster response to the supply voltage disturbance.2.For certain firing schemes, the rectifier and the control circuittogether have a constant gain under continuous of 5 percent.Under discontinuous conduction, the gain reduces. The higher the reduction is in the conduction angel, the greater the reduction is in the gain. The drive response becomes sluggish in discontinuous conduction and progressively deteriorates as the conduction angle reduces. If an attempt is made to design the drive for discontinuous conduction current control loop providesa closed loop around the rectifier and the control circuit, andtransient response of the drive with the inner current loop is superior to that with the current-limit control.3.In the current-limit control, the current must first exceed thepermissible value before the current-limit action can be initiated.Since the firing angle can be changed only at discrete intervals,substantial current overshoot can occur before the current limiting becomes effective.Small motors are more tolerant to high transient current. Therefore, to obtain a fast transient response is then needed only for abnormal values of current. In such cases because of the simplicity, current-limit control is employed.Both the schemes have different responses for the increase and decrease in the speed command. A decrease in speed command at the most can make the motor torque zero; it cannot be reversed as braking is not possible. The drive decelerates mainly due to the load torque. When load torque is low, the response to a decrease in the speed command will be slow. These drives are therefore suitable for application with large load torque, such as paper and printing machines, pumps, and blowers.。

自动化专业英语复习提纲
自动化1021、1022班《自动化专业英语》课程复习提纲考核方式：开卷考试考试范围包括：CHAPTER 1 FUNDAMENTALS OF AUTOMATIC CONTROLCHAPTER 2 MEASURMENT AND ACTUATORSCHAPTER 4 COMPUTER CONTROL SYSTEMS（自学）CHAPTER 5 AUTOMATIC CONTROL SYSTEMS（第五章只考其中的单元5.1 Mathematical Modeling of Physical System）（自学）考试题型：PART1:自动化专业词汇英译汉（每小题1分，共30分）PART2:自动化专业词汇汉译英（每小题1分，共30分）PART3:短文英译汉（每小题10分，共40分）CHAPTER 1和CHAPTER 2是上课讲过的内容，作为重点复习，专业词汇部分的英译汉和汉译英会考到课上讲过的词汇和每个单元后面word and expressions 里的词汇。
CHAPTER 4和CHAPTER 5（5.1）属于自学内容，考试偏重比例较小，专业词汇的英译汉和汉译英只考每个单元后面word and expressions里的词汇。
短文翻译部分是课文中的内容，列出几个重点：单元1.1（第1页最后一段）The control objective for the stirred-tank heater is to keep the exit temperature T at a constant reference value Tr. The reference value is referred to as a set point in control terminology. Next we consider two questions.单元1.3（第23页第一段）An important consequence of feedback control is that it can cause system oscillatory response. If the oscillation has a small amplitude and damps out quickly then the control system performance is generally considered to be satisfactory.单元1.3（第24页中间靠下的地方）Before presenting various stability criteria, we introduce the following definition for unconstrained linear systems. We use the term "unconstrained" to refer to the ideal situation where there are no physical limits on the output variable.单元1.4（第33页第二段）The skills needed for good design entail experience, intuition and esthetic sensibility. They are not easily learned from books. The most you ought to expect from any book on design (include this one) is to learn about some useful tools.单元1.5（第45页第一段）After a control system is installed the controller settings must usually be adjusted until the control system performance is considered to be satisfactory. This activity is referred to as controller tuning or field tuning of the controller. Because controller tuning is usually done by trial and error, it can be quiet tedious and time-consuming.单元2.2（第66页第二段）Continuous level monitoring measures the level of the liquid on an uninterrupted basis. In this case the level of the material will be constantly monitored and hence, the volume can be calculated if the cross-sectional area of the container is known.单元4.1（第142页第二段）The sampler is virtual. On a regular basis, under control of the RTOS, values of the AOT output are extracted from the database and routed through to the D/A converter. The sampler is held open long enough for the conversion to take place.。

句子翻译：40分，8题1:P2A common method of analyzing an electrical network is mesh or loop analysis.The fundamental law that is applied in this method is Kirchhoff's first law,which states that the algebraic sun of thevoltages around a closed loop is0,or,in any closed loop,the sum of the voltage rises must equal the sum of the voltage drops.Mesh analysis consists of assuming that currents~termed loopcurrents~flow in each loop of a network,algebraically summing the voltage drops around each loop,and setting each sum equal to0.分析电网络的一般方法是网孔分析法或回路分析法。
应用于此方法的基本定律是基尔霍夫第一定律，基尔霍夫第一定律指出：一个闭合回路中的电压代数和为0，换句话说，任一闭合回路中的电压升等于电压降。
网孔分析指的是：假设有一个电流——即所谓的回路电流——流过电路中的每一个回路，求每一个回路电压降的代数和，并令其为零。
2: P17Alternatively,suppose that there had been attached to each pilot’s seat an electronic device that pr ovided an output voltage which is V1when the seat is occupied and V2when the seat is not occup ied.Let us attach the designation“true”to the voltage level V2so that the level V1is“false”.Let us further construct an electric circuit with two sets of input terminals and one set of output termi nals.The circuit is to have the property that the output voltage will be V2if and only if both inputs ,i.e.,one input AND simultaneously the other,are at the level V2.Otherwise the output is V1 Finally let us connect the inputs to the devices on the chairs of pilots A and B and arrange that an alarm bell,connected to the output Z,respond when the output is V2(“true”)and not otherwise. We have then constructed a circuit which performs the AND operation and is capable of making the logical deduction that the plane is unpiloted when,indeed,both pilots leave the cockpit换句话说，假设每一位飞行员座位下面有一个电子装置，当座位上有人时，其输出电压为V1，当座位上无人时，其输出电压为V2。
