磁流变半主动悬架变负载MRAC控制
MRAC of magnetorheological semi-active suspension with variable loads
摘要
Abstract
In response to the uncertainty problem of load change affecting the performance of the vehicle,a mathematical model of quarter vehicle semi-active suspension containing load force is established.Magnetorheological(MR)damper is a-dopted as the semi-active component,and model-referenced adaptive control(MRAC)is used to attenuate the vibration,and the stability of the system is proved by Liapunov's theorem.The simulation analysis under variable loads was carried out u-sing the root mean square values of body acceleration,suspension displacement and tire dynamic load as evaluation indexes.The results show that under random road excitation,the three performance indexes of the MRAC-based suspension are signif-icantly reduced compared with the passive suspension under zero load,1kN load and 2kN load,respectively.关键词
