基于模糊PID主动控制的仿真及应用

Simulation and Application Based on Fuzzy PID Active Control

针对电气化铁路中的接触网-受电弓系统,提出模糊主动控制、PID主动控制,并结合两者的优点建立模糊PID主动控制;根据受电弓的特点,建立受电弓三元质量块模型,并推导出受电弓的动力学方程、状态空间方程和传递函数;利用Simulink仿真手段,对被动控制、模糊主动控制、PID主动控制、模糊PID主动控制的弓网系统动态性能进行仿真研究。仿真结果表明:模糊PID主动控制策略可以最大程度的降低弓网系统接触压力的波动,提高弓网系统的受流质量。

For the pantograph- catenary system of the electrified railway, the fuzzy active control model, proportional integral differential（PID） active control model were discussed, and combined the advantages of these two models, the fuzzy PID active control was established. According to the characteristics of the pantograph, established the pantograph mass model, and derived the dynamic equation, state space equation and transfer function of the pantograph. Simulation study of dynamic performance of the pantograph-catenary system under the passive control, fuzzy active control, PID active control and fuzzy PID active control are made with software simulink. The research results show that the dynamic performance and quality of current collection of the pantograph-catenary system can be improved the most obviously with fuzzy PID control.
