摘要
结合普通PID控制和模糊控制理论,在普通PID控制原理的基础上,提出了利用模糊控制理论中的Sugeno模 糊推理实现模糊PID分层控制。此算法既结合了普通PID控制算法中所具有的结构简单、易实现、易使用的特点;同时又 加入了专家经验等模糊智能控制的思想,使整个控制算法在控制过程中能根据实际所处的控制阶段及控制要求来动态地调 整PID各参数。针对不同的仿真对象进行了仿真实验,仿真结果表明:使用此算法,整个控制过程性能参数有了很大的提 高,超调明显减小,调节时间缩短,反应速度加快。由于此算法实现方便,原理简单,而且控制效果好,在实际的工业控 制过程中具有非常广泛的应用范围,值得推广和借鉴。
This paper combines the normal PID control with Fuzzy control theory. On the basis of principle of normal PID control. It brings forward an idea of realizing PID delaminated control by Sugeno fuzzy illation of fuzzy control theory. This Algorithm not only has the characters of normal PID control, such as the simple structure, easy to realize and use promptly; but merges the experts′ experiences. This algorithm can dynamically change the PID parameters with the different stage and different status. Through imitating this algorithm in different experiments, the performance parameters of the course is improved a lot, adjusting time is shortened, the reaction speed is fast than before obviously. Because it is convenient to realize this algorithm, the principle is simple, the control is effectual, this algorithm has a very extensive range of application in the course of real industrial control process, worth popularizing and taking advantage of reference.
