摘要
Abstract
With the increasing application of damping variable semi-active suspension,the traditional vehicle body height control strategy which is without consideration of damping factor can’t meet the requirement of control. In order to explore the effect of damping on vehicle body height control,the step responses of the body height on different damping states were comparatively studied;and compared with the control effect results of the same PID control parameters on different damping states,the results show that the damping has obvious influence on the body height adjustment process, and when the damping is changed,the same PID control parameters can no longer meet the requirements of the control system. Therefore we used the genetic algorithm to tunn the PID parameters of the body height control strategy under different damping states,and the results show that,with the increase of damping coefficient,the proportional coefficient Kp and differential coefficient Kd should be moderately increased.关键词
