摘要
研究主动悬架自适应于路面输入和车辆参数变化，从而进一步改进车辆性能的潜力，以及车辆参数变化对车辆系统输出的影响。仿真结果表明了在主动悬架的最优控制设计中，其控制律参数自适应于路面输入的有效性，以及控制器设计中车辆参数估计的必要性。
This paper investigated the potential performance improvements from adaptation for an active vehicle suspension to changes in road input and variations ofvehicle parameters. Simulation results showed that for anoptimal controller design of an active suspension, theadaptation of control gains to road input conditions, including vehicle forward speed and road surface roughness .can offer vehicle performance improvements significantly .but the benefits of adaptation to variation of vehicle parameters are relatively small. However, the significant effects of vehicle parameter on system outputs wereshowed, which implies the need of parameter estimation.Therefore, for any practical active suspension design,some form of adaptation will inevitably be required to obtain further performance improvements.
