【Abstract】 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.更多还原
