The Intelligent Control Strategy For The High Performance AC Servo System

As the development of AC motor control strategies and the appearance of Vector Control Theory which stands for the advanced speed-regulating theory, the performance of AC motor control system had been progressed essentially.AC motor is a high order,nonlinear,coupling system,the Vector Control accomplishes its decoupling control. It makes it possible to control the AC motor high precisely.In this Article, the AC motor control system based on the Vector Control is mainly presented in Chapter 2. The excellent design of DC control system is also used to make up a simulation model of the AC servo system decoupling .As the development of the technology and science , it demands more and more high quality of AC Servo system(such as fast responce,non_over_shout,non_osillation etc.). So the normal position controller can't satisfy these demands.Because Servo System is a fast response system, the control strategies can't be too complicated. In this character, Fuzzy controller is designed in chapter 3. In this chapter the results of fuzzy control is discussed. A convienent and effective muti-controller coordinating control system which is base on the fuzzy rules is taken to overcome the position unaccuracy which only fuzzy controller is used.The results of simulation and experiment demonstrate its effection. As the Neural Networks had been used in the control field,in Chapter 4 neuro controller and its new control algorithems which improves dynamic tracking performance are used in our servo system.The simulation results and experiment results show its effection and reliability. An UnvariableControlTheorybased neural netwoks forword control of servo system is also presented in Chapter 4, and the simulation results are also given.The design based on DSP which accomplishes the Neural Netwoks algorithms is also given.
