摘要
针对异步电动机调速系统的非线性和结构参数易变等特点,将模糊控制和PID控制的简便性、灵活性结合起来,设计了模糊PID调速系统的双闭环模糊控制仿真模型,建立了基于Matlab Simulink的系统仿真模型,并对模型进行了多方面性能的仿真研究。仿真结果表明,该模糊控制系统仿真模型具有良好的给定适应性、鲁棒性;并且提高了非线性系统的动、静态特性,使系统获得了较好的性能。
Considering the nonlinear and the easy variance of induction motor parameters,fuzzy control is used to design a fuzzy PID controller of the recovering system when fuzzy logic controller and PID controller are combined together,which has simple structure and high robustness.The simulation model based on Matlab Simulink is built to study some performance of the system.Simulation results demonstrate its good adaptability and robustness;improve the dynamic and static performance of control system.
