摘要
提出一种结合模糊控制与PID控制的模糊PID控制器。在模糊PID控制器的设计中,分析了模糊PID控制器的工作原理;确定了模糊论域与隶属度函数;制定了控制规则;分析了模糊PID控制器参数自整定原理。最后采用PID与模糊PID对二阶系统进行了仿真分析。仿真结果表明模糊PID控制器的控制效果与常规PID控制器相比具有超调量小、调整时间短等优点,改善了系统的动态响应性能。
This paper proposes a fuzzy PID controller combined with fuzzy control and PID control. In the design of fuzzy PID controller, the working principle of fuzzy PID controller is analyzed. The fuzzy domain and membership function are determined. The control rules are established. The fuzzy PID controller parameters self-tuning principle is analyzed. Finally, the second-order system is simulated and analyzed by PID and fuzzy PID. The simulation results show that the control effect of the fuzzy PID controller has the advantages of small overshoot and short adjustment time compared with the conventional PID controller, which improves the dynamic response performance of the system.
