基于电磁直线作动器的主动悬架控制方法研究
Research on control strategy used in the active suspension with an electromagnetic linear actuator
摘要
Abstract
In order to achieve the tracking output of electromagnetic resistance in the active suspension with an electromagnetic linear actuator(EMLA),and improve the performance of suspension,the hierarchical control system is proposed.Based on a quarter active suspension dynamic model and the EMLA drive circuit model,the hierarchical control system is designed by combining LQG controller and Fuzzy-PID controller to track optimal active force automatically.The design of active suspension control system of the EMLA is presented,the model is constructed by using MATLAB/Simulink,then it is simulated and tested through specific platform.The results show that the vibration reduction characteristic of suspension is improved obvious-ly by using the mehtod,and the acceleration of car body and the suspension working space are reduced drastically compared with passive suspension.The research result has certain reference for the study of the active control of the electromagnetic suspension.关键词
