Time Delay Compensation Control of Semi-active Suspension with Vehicle Electro-hydrostatic Actuator
摘要
Abstract
To improve the ride comfort and stability of vehicles,a kind of the semi-active suspen-sion with EHA was designed and the mechanical property tests of the electro-hydrostatic actuator were completed.The bond graph models of the time delay fuzzy control for EHA semi-active suspen-sion were established.The critical time delay of the EHA semi-active suspension was calculated.The time delay impacts on the amplitude-frequency characteristics and vibration isolation properties were analyzed.The time delay fuzzy Smith predictive compensation controller was designed.The simulation analyses of the time delay compensation fuzzy control for the EHA semi-active suspension were done. The results show that the EHA semi-active suspension has good damping controllability.However, with the increase of time delay,the “j ump vibration”phenomenon happens to the suspension system. Under the time delay compensation fuzzy control of the EHA semi-active suspension,the sprung mass acceleration drops by about 30% and the tire dynamic load drops by about 20%.关键词
