摘要
该文首先通过建立模糊规则和进行模糊推理来确定PID控制器的参数 ,而后由PID控制律直接确定控制作用。文中将模糊逻辑工具箱和MATLAB函数相结合 ,方便地实现了汽温控制系统的计算机仿真。仿真结果表明 ,这种方法简单 ,易于实现 ,能够获得比常规的具有固定参数的PID控制更好的控制效果 。
This article presents a design method about fuzzy PID control. The met hod can be divided two steps: firstly, build the fuzzy turning rules by simulati on and analysis, and obtain the parameters of PID controller by reasoning, then the control effect can be determined by the PID control laws. In this article, f uzzy logical toolbox and MATLAB function are used together to implement the comp uter simulation of steam temperature control system. The simulation results show that this method improve the performance of the control system and can be easil y carried out ; furthermore the control system which uses the fuzzy PID contro ller has better performance than that of the traditional PID control system.
