模糊PID控制器及在汽温控制系统中的应用研究

本文将模糊控制和常规ＰＩＤ控制两种设计思想融合起来，提出一种基于模糊规则的ＰＩＤ控制器的设计方法。这种方法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。仿真结果表明，用本文方法所设计的汽温控制系统比常规的具有固定参数的ＰＩＤ控制具有更加优良的性能。

Fuzzy PID Controller and ha Appllcation Study in Temperature Control System

Incooprating the fuzzy control and the conventional PID control, this Paper presents a design method of the fuzzy PID controller which is based on the fuzzy tuning rules and formed by integrating two above control ideas. The design method about fuzzy PID control can be divided two steps: firstly, building the fuzzy tuning rules by simulation and analysis, and to obtain the parameters of PID controller by reasoning, then the control effect can be determined by the PID control law. The simulation results show that the control system which uses the fuzzy PID controller has better performance than that of the traditional PID control system.
