【Abstract】 In this paper, the parameter estimation algorithms of memory attenuat ion, recursion and least square as well as the self-correcting control algorith m s of generalized weighing and minimum variance are applied to an active electro - hydraulic suspension with the pressure servo valve controlled hydraulic cylinder used as actuator. The results of theoretical analysis and numerical simulation show that the control scheme is feasible due to its good adaptability to a numbe r of time-varying parameters.更多还原
