摘　　要：应用Adams创建汽车1/4悬架模型,通过Matlab/Simulink搭建控制框图,实现车辆的半主动和被动控制。其中半主动控制策略由内环和外环2个部分实现,外环控制由模糊控制率实现,根据悬架模型反馈的状态变量输出目标控制力;内环体现MR阻尼器的动力学特性,对外环产生的目标控制力进行跟踪,建立了MR阻尼的力简化模型,并用PID控制算法控制跟踪误差。To build semi-active and passive vehicle control, created a quarter vehicle suspension model by Adams,constructed the block diagram of controlling by Matlab/Simulink. The semi-active control strategy was implemented by two loops：outer loop and inner loop. The outer loop control was implemented by fuzzy control, and according to the feedback state variables of the suspension model,calculated the target control force; Inner loop which reflects the dynamic characteristics of MR damper was used to track the the target control force. A simplified force model of MR damping was established and used the PID control algorithm to track error.
