摘　　要：针对汽车发动机的减振问题,设计了自抗扰控制器,建立了二自由度磁流变悬置减振控制系统模型。通过仿真实验,研究了在起动时不同控制策略作用下的车身振动加速度和悬置动行程问题,结果表明:基于自抗扰控制的磁流变悬置系统减振效果最优,具备更好的舒适性。Aiming at the vibration problem of automobile engine,a two-degree of freedom magnetorheological suspension damping control system was established.An automatic disturbance rejection controller was designed.Through simulation experiments,the vehicle body vibration acceleration and suspension stroke under different control strategies during engine starting were studied.The results showed that the magnetorheological suspension based on automatic disturbance rejection control has the best damping effect and comfort.
