说明：  AC induction motors are the most common motors used in industrial motion control systems, as well as in main powered home appliances. Simple and rugged design, low-cost, low maintenance and direct connection to an AC power source are the main advantages of AC induction motors. The speed control of these motors has been of great importance in order to run the motors at desired speeds. Among the various methods of speed control V/F control of induction motor is the most efficient one, in which V/F ratio is kept constant. In this project we studied about this V/F control of an induction motor and simulated it in the matlab Simulink and controlled the torque and speed of induction motor. This technology continued to be taken up further improvements all over the world till very recently.

题目：已知被控对象为 1/(10s+1)*exp(-0.5s)。假设系统给定为阶跃值r＝30，采样时间为0.5s，系统的初始值r(0)＝0。试分别设计： (1)常规的PID控制器； (2)常规的模糊控制器； 分别对上述2种控制器进行Matlab仿真，并比较控制效果 (Topic: Known charged object is 1/(10s+1)* exp (-0.5s). Assume that the system is given as the step value r = 30, the sampling time of 0.5s, the system the initial values ​ ​ of R (0) = 0. Trial were designed: (1) conventional PID controller (2) conventional fuzzy controller Matlab simulation of the two kinds of controllers, respectively, and compare the control effect)
