摘要
提出一种最优模糊PID控制器的设计,该方法将混沌因子引入到模糊PID控制器参数域的全局优化搜索方法中,在优化过程中不断缩小寻优区间以提高搜索效率,能较快搜索到全局最优解。最后,对延迟的三阶系统进行仿真,并与Ziegle-NichoLs规则的PID控制相比较,控制结果说明该方法是有效可行的。
An optimal design scheme of fuzzy PID controller had proposed in the paper. The method introduces the chaos factors to searching for global optimal field of parameters of fuzzy PID controller. The high efficiency is obtained by continually minimizing the optimal searching region, by which the global optimal value can be obtained quickly. Finally, the delayed third order system is simulated and compared with PID controller of Ziegler-Nichols rule. The result of control shows that the method is effective and feasible.
