Mechatronics Integration

Mechatronics is the integration of mechanical, electrical, and software technologies in the design and manufacture of complex systems. Mechatronic systems are created by incorporating sensors, actuators, and controllers into a single system, which facilitates the use of feedback control to improve system performance. The advantages of mechatronics include improved precision, speed, and reliability in a wide range of applications.

Mechatronics integration involves the development and implementation of a system that combines mechanical, electrical, and software components. This process requires the expertise of mechanical engineers, electrical engineers, and software engineers who work together to develop a cohesive system. The integration of these technologies allows for the creation of complex systems that are more efficient, accurate, and reliable than traditional systems.

Electric Power Steering system

1.History

In automobile development course, Steering system experienced four stages of development: from the initial mechanical Steering system (for your DNS setting Steering, abbreviation ) development for Hydraulic Steering system (Hydraulic Power Steering, abbreviation HPS), then again appeared electronically controlled Hydraulic Steering system (Electro Hydraulic Power Steering, abbreviation EHPS) and Electric Power Steering system (Steering, room Power as EPS). Assemble mechanical steering system of car parking and low-speed driving, when the driver's steering control burden too heavy, in order to solve this problem, the American GM in the 1950s took the lead in the car hydraulic steering system. But, hydraulic steering system can't juggle vehicles to speed portability and high speed, so the steering stability Koyo in Japan in 1983, with the company introduced the application of speed sensing function of hydraulic steering system. This new type of steering system can provide speed increased with the decreasing steering, but complicated structure, cost is higher, and cannot overcome hydraulic system itself has many shortcomings, is a cross between a hydraulic steering and electric power steering the transition between the products. In 1988, Japan Suzuki company first in small cars equipped with Cervo Koyo company development on the steering column, power type electric power steering system; In 1990, Japan Honda NSX in sports car company adopted self-developed rack power type electric power steering system, henceforth unveils the electric power steering in cars applications history

electronically commutated motor or brushless servomotor
The primary limitation of the DC servomotor is the mechanical commutator:
• brush replacement • brush run-in after replacement, • brush RFI (radio frequency interference) • voltage/current limitations.
DC servomotors VS Brushless servomotors
• The traditional permanent magnet DC servomotor has been the industry workhorse for many decades in high performance servo drive applications. The primary reason for this is that the DC servomotor is very easy to control using adjustable DC voltage.
• By eliminating the DC motor’s mechanical commutator and armature winding on the rotor, the brushless motor design results in lower rotor inertias, higher rotor speeds, and higher motor supply voltages compared to the conventional DC servomotor.

Furthermore a prophecy method for f nd ng the steady-state and trans ent thermal characteristics of the LSRM are presented.

I.I NTRODUCTION

LSRMs are an attractive alternative to linear induction or synchronous machines due to lack of windings on the stator or translator structure, easier manufacturing and maintenance. However LSRM has some downsides such as high force ripple, vibration, acoustic noise and need of power electronic converters. In this paper a novel structure for a longitudinal flux double sided LSRM is proposed to mitigate the force ripple. For the force control, force distribution function (FDF) is used and compared with the conventional FDFs. A trapezoidal velocity profile is used to control the travel position smoothly during the ascent, descent, and halt operations.

The three-phase induction motor speed control method

Three-phase asynchronous motor speed formula: N = 60f / p (1-s) Can be seen from the above formula, change the power supply frequency f, motor pole number p and the slip s may be too much to change the speed of purpose. From the speed of the essence of view, is simply a different way to change speed synchronous AC motor does not change the sync transfer speed or two.

Control of Electric winch

For motor control, we know the best way is to use the style buttons to move the many simple manual console. And this console, in some applications may still be a good choice, as some complex control headache can also be used. This article describes in your design, build or purchase winch controller, you have the motor's basic electrical equipment and you will need to address the user interface command addressed.

First, the manual should be a manual control console type, so if you remove your finger buttons, hoist will stop. In addition, each control station equipped with an emergency need to brake, hoist the emergency brake to cut off all power, not just the control circuit. Think about it, if the hoist at the stop, it did not stop, you do need a way to cut off the fault line protection power. Set the table in the control of a key operated switch, is also a very good idea, especially in the line leading to the

determine the phase currents of a variable-reluctance motor with respect to position and torque set points. Filicori et al. [4]proposed a dynamical torque controller based on a flux observer which minimizes copper losses or the maximum motor-feeding voltage. Le1 Huy et al. [lo, 3 reduces the torque ripple harmonics for brushless DC motor by using several drive current waveforms. The main tool in the control of synchronous motors is a transformation of phase currents via the ‘d-q transformation’ 191. Since this transformation linearizes only an ideal motor with perfectly sinusoidally distributed magneto-motive force, another torque set point is cascaded to cancel torque ripples. This method has been successfully implemented on the previous version of our McGill/MIT motor at MIT [7]. Less than f l N m ripple has been reported, however, in contrast to this paper, no attempt to minimize power dissipation was made. In a previous paper [I], we presented an alternative approach to torque ripple minimization, which was based on linear magnetics only. In contrast, the approach presented here is applicable to nonlinear magnetics as well. This paper is organized as follows: Section 2 presents an optimal nonlinear mapping (commutation law) from desired torque and position to motor phase angles with minimum copper losses. This mapping is available in closed form for linear magnetics. In Section 3, the experimental hydraulic dynamometer testbed is described, and the phase torque-angle and torque-current characteristics are identified experimentally for the McGill/MIT synchronous directdrive motor. The performance of the proposed commutation to produce virtually ripple-free torque and to yield precise position tracking is demonstrated in Section 4 experimentally.

Industrial Robots and Electric drive system

There are a variety of definitions of the term robot. Depending on the definition used, the number of robot installations worldwide varies widely. Numerous single-purpose machines are used in manufacturing plants that might appear to be robots. These machines are hardwired to perform a single function and cannot be reprogrammed to perform a different function. Such single-purpose machines do not fit the definition for industrial robots that is becoming widely accepted. This definition was developed by the Robot Institute of America:

A robot is a reprogrammable multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks.

Electric Motors

Each type of motor has its particular field of usefulness. Because of its simplicity, economy, and durability, the induction motor is more widely used for industrial purposes than any other type of ac motor , especially if a high-speed drive is desired.

If ac power is available, all drives requiring constant speed should use squirrel-cage induction or synchronous motors because of their ruggedness and lower cost. Drives requiring varying speeds, such as fans, blowers, or pumps, may be driven by wound-rotor induction motors. However, if there are machine tools or other machines requiring adjustable speed or a wide range of speed control, it will probably be desirable to install dc motors on such machines and supply them from the ac system by motor-generator sets or electronic rectifiers.

The DC Tachogenerator is a speed transducer, which develops DC voltage proportional to speed of the motor connected to it. Permanent Magnetic field eliminates the need of external excitation and offers extremely reliable and stable outputs. The accuracy of the tachogenerator decides the maximum accuracy of speed of the controlled machine. They are widely used for feedback and display purposes.

DC servo motors are normally used as prime movers in computers, numerically controlled machinery, or other applications where starts and stops are made quickly and accurately. Servo motors have lightweight, low-inertia armatures that respond quickly to excitation-voltage changes. In addition, very low armature inductance in these servo motors results in a low electrical time constant (typically 0.05 to 1.5 msec) that further sharpens servo motor response to command signals.

伺服电机

1. 伺服电机的定义

伺服电动机又称执行电动机，在自动控制系统中，用作执行元件，把所收到的电信号转换成电动机轴上的角位移或角速度输出。分为直流和交流伺服电动机两大类，其主要特点是，当信号电压为零时无自转现象，转速随着转矩的增加而匀速下降。伺服电机在伺服系统中控制机械元件运转的发动机. 是一种补助马达间接变速装置。伺服电机可使控制速度, 位置精度非常准确。将电压信号转化为转矩和转速以驱动控制对象。转子转速受输入信号控制，并能快速反应，在自动控制系统中作执行元件，且具有机电时间常数小、线性度高、始动电压低等特点。

2. 伺服电机工作原理

1.伺服主要靠脉冲来定位，基本上可以这样理解，伺服电机接收到1 个脉冲，就会旋转1 个脉冲对应的角度，从而实现位移，因为，伺服电机本身具备发出脉冲的功能，所以伺服电机每旋转一个角度，都会发出对应数量的脉冲，这样，和伺服电机接受的脉冲形成了呼应，或者叫闭环，如此一来，系统就会知道发了多少脉冲给伺服电机，同时又收了多少脉冲回来，这样，就能够很精确的控制电机的转动，从而实现精确的定位，可以达到0.001mm有刷电机成本低，结构简单，启动转矩大，调速范围宽，控制容易，需要维护，但维护方便（换碳刷），产生电磁干扰，对环境有要求。无刷电机体积小，重量轻，出力大，响应快，速度高，惯量小，转动平滑，力矩稳定。控制复杂，容易实现智能化，其电子换相方式灵活，可以方波换相或正弦波换相。电机免维护，效率很高，运行温度低，电磁辐射很小，长寿命，可用于各种环境。

2. 交流伺服电机也是无刷电机，分为同步和异步电机，目前运动控制中一般都用同步电机，它的功率范围大，可以做到很大的功率。大惯量，最高转动速度低，且随着功率增大而快速降低。因而适合做低速平稳运行的应用。

3. 永磁交流伺服电动机简介

20 世纪80 年代以来，随着集成电路、电力电子技术和交流可变速驱动技术的发展，永磁交流伺服驱动技术有了突出的发展，各国著名电气厂商相继推出各自的交流伺服电动机和伺服驱动器系列产品并不断完善和更新。交流伺服系统已成为当代高性能伺服系统的主要发展方向，使原来的直流伺服面临被淘汰的危机。90 年代以后，世界各国已经商品化了的交流伺服系统是采用全数字控制的正弦

波电动机伺服驱动。交流伺服驱动装置在传动领域的发展日新月异。永磁交流伺服电动机同直流伺服电动机比较，主要优点有：⑴无电刷和换向器，因此工作可靠，对维护和保养要求低。⑵定子绕组散热比较方便。⑶惯量小，易于提高系统的快速性。⑷适应于高速大力矩工作状态。⑸同功率下有较小的体积和重量。

自从德国MANNESMANNRexroth公司的Indramat分部在1978年汉诺威贸易博览会上正式推出MAC永磁交流伺服电动机和驱动系统，这标志着此种新一代交流伺服技术已进入实用化阶段。到20 世纪80 年代中后期，各公司都已有完整的系列产品。整个伺服装置市场都转向了交流系统。早期的模拟系统在诸如零漂、抗干扰、可靠性、精度和柔性等方面存在不足，尚不能完全满足运动控制的要求，近年来随着微处理器、新型数字信号处理器
