基于Simulink的主动径向转向架控制方法研究

摘要

Based on Simulink in MATLAB ,the simulation model of an active steering bogie control system was set up .Due to the time variation and nonlinear of control system ,PID control method ,fuzzy control method and mixed fuzzy-PID control method were respectively used in the simulation process .The comparative analysis shows the mixed fuzzy-PID control method has better control effect than the two others ,with shorter settling time ,faster response ,and better stability .%基于MATLAB中的Simulink模块，对主动径向转向架的控制系统建立有效的仿真模型。由于该控制系统的时变性与非线性等特点，在仿真过程中采用了PID控制方法、模糊控制方法以及混合型模糊-PID控制方法。经比较分析表明，采用混合模糊-PID控制方法的控制系统调节时间较短，阶跃响应较快，稳定性更好。
