摘　　要：将直线电机的直接推力控制方法运用于主动悬架控制系统,分别设计了主动悬架最优控制器和直线电机直接推力控制器,两个控制器结合成为主动悬架的电磁作动器控制系统。建立了1/4汽车主动悬架模型,利用Matlab/Simulink进行仿真,结果表明直线电机作动器能根据车身的振动主动输出相应的电磁力,因此直线电机直接推力控制运用于主动悬架控制系统是可行的。The direct thrust control method of the linear motor was used in control system of vehicle active suspension, respectively, the optimal controller of active suspension system and linear motor direct thrust controller were designed, combining the two controllers into the control system of active suspension actuator. A two-degree-of-freedom quarter-car model with active suspension system was established. The model for simulation was established by Matlab/Simulink. It is indicated that linear motor actuator can produce the corresponding magnetic force according to the vibration of bodywork, therefore the direct thrust control of linear motor used in active suspension control system is feasible.
