摘要
本文研究一种新型模糊PID控制器在一般热工对象中的应用问题。由于热工对象存在参数时变的问题 ,因此本文采用仿真方法针对对象参数时变的情况进行了控制器的鲁棒性分析。针对多变量输入 ,模糊控制规则多而控制器不易实现这一问题 ,本文提供了一种结构简单、性能优良的一维模糊控制器与PID控制相结合的控制策略。这种控制结构很好的解决了模糊控制不跟踪输入的问题。
In this paper,application of a fuzzy PID control system used in thermal plants is studied.Because the parameter of the thermal plant is time-varying parameters,this paper discussed the robustness of the new control method with simulation experiments.In common fuzzy control methods,there are many problems:the input is complex,the realization of controller is not easy,control rules are lots of.Aim at the problems mentioned above,this paper provided an simple structure fuzzy PID control method which have excellent tracking behavior.
