摘　　要：针对伺服液压车辆主动悬架系统(active vehicle suspension system,AVSS),在非线性的伺服液压四分之一车辆主动悬挂系统模型的基础上,提出了一种基于受控随机搜索算法的PID控制器设计,以便提高车辆乘坐舒适性以及操纵性能。提出PID控制器的控制参数能根据系统运行状态的变化,进行优化调整。在相同路面干扰方面情况下,将基于提出PID控制器的主动悬架与被动悬架进行了比较。模拟结果表明,基于提出PID控制的主动悬架能有效降低车身加速度和轮胎动载荷,有效改善了车辆的乘坐舒适性以及操纵性能。According to the hydraulic servo vehicle active suspension system （AVSS）, based on the system model of nonlinear active suspension servo hydraulic 1/4 vehicles, a PID controller based on the controlled random search algorithm is proposed, in order to improve vehicle ride comfort and handling performance. The control parameters of PID controller can be adjusted according to the change of the system running state. In the case of the same road disturbance, the active suspension and passive suspension based on the proposed PID controller are compared. The simulation results show that the active suspension based on PID control can effectively reduce the acceleration of the vehicle body and the dynamic load of the tire,and effectively improve the ride comfort and handling performance of the vehicle.
