基于磁流变阻尼器的半主动悬架控制与仿真
Control and simulation of semi-active suspension based on MRF damper
【摘要】 基于磁流变阻尼器的Bouc—W en模型,设计了半主动悬架系统的控制器。该控制器由系统控制器和阻尼器控制器组成,系统控制器采用二次型最优控制LQR算法,阻尼器控制器采用基于Signum函数的方法。进行了基于Simulink的仿真分析,通过比较被动控制和主动控制,表明该半主动控制算法具有良好的控制效果。
【Abstract】 A controller was designed for the semi-active suspension system based on the Bouc—Wen model of magneto-rtheological fluid(MRF) damper.The controller consists of a system controller basing on LQR algorithm and a damper controller basing on Signum function method.Basing on Simulink simulation and compared with passive and active control,the semi-active cotrol algorithm shows good control effect.
