本文采用1/4车模型对天棚阻尼器和主动悬架的动力学性能进行分析。针对执行器的非线性特性,探讨了微分几何法和反馈线性化法在主动悬架控制中的应用。在系统控制设计中采用了离散滑模法。仿真结果显示非线性控制律能有效地改善主动悬架的隔振特性。
In this paper, the 1/4-car model is used to analyze the dynamic performance of ceiling damper and active suspension. According to the nonlinear characteristics of actuator, the application of differential geometry method and feedback linearization method in the active suspension control is discussed. In the system control design using discrete sliding mode method. The simulation results show that the nonlinear control law can effectively improve the vibration isolation characteristics of the active suspension.
