摘要
为了研究高速列车主动悬架系统横向振动控制,将研究对象简化为二自由度1/4车悬挂模型,研究了高速列车车体的横移、侧滚为变量的列车悬挂控制系统,采用德国轨道谱作为列车的激励拟合。算法控制器选择方面,在PID控制和模糊控制的基础上,建立模糊PID控制,并建立了基于模糊PID控制的高速列车主动悬架横向振动控制系统,通过MATLAB仿真生成关系曲线,验证了模糊PID控制算法具有更好的控制效果。
In order to study the lateral vibration control of the high-speed train active suspension system,this paper simplifies the research object into a two degree of freedom 1/4 vehicle suspension model,studies the train suspension control system with the lateral displacement and roll of the high-speed train body as variables,and uses the German track spectrum as the excitation fit of the train.Algorithm controller selection,based on PID control and fuzzy control,this paper establishes fuzzy PID control,and establishes a high-speed train active suspension lateral vibration control system based on Fuzzy PID control.The relationship curve is generated by MATLAB simulation,which verifies that the fuzzy PID control algorithm has better control effect.
