摘　　要：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, a quarter-car model is used to analyze dynamic performance of active suspension and skyhook damper. In view of nonlinearity of the actuator, the applications of differential geometry and accurate feedback linearization procedures to active suspension system control are investigated. A discrete time sliding mode method is adopted for the control design of the system. Simulation results of nonlinear control indicate that the ride quality of auto mobile is improved remarkably.
