模糊PID控制在伺服系统中的应用

在现行伺服系统中多采用PID控制方式。传统的PID控制系统虽然具有稳定、结构简单等优点，但是当被控对象参数发生改变或者受非线性因素影响发生变化时不能随之改变，无法满足高性能、高精度的要求。模糊PID控制方式已经在许多领域得到运用。将模糊PID控制与传统PID控制进行对比，利用模糊推理方法实现了对PID参数的在线自动整定，并且在Matlab软件下，将该控制器在运动控制系统中的应用进行了仿真，结果表明该控制能使系统达到满意的控制效果。

Application of Fuzzy PID Control in Servo System

Current servo system almost adopts PID control method.The traditional PID control system has the advantages of stabilization and simple structure,but it can't change immediately when the parameters of the control object change with the nonlinear factor,so the traditional PID control system can't satisfy the request of the high performance and high definition.The fuzzy PID control has already got the usage in many realms.This paper compares the fuzzy PID with traditional PID control,realizes the online automatic tuning by the control method of fuzzy inference method,and simulates the application of the control in motion control system with Matlab.The results of simulation shows that the control gives a good control effect to the system.
