摘要：
Robust compensation control was proposed for a class of vehicle active suspension systems with input delay. First, according to the half vehicle active suspension dynamic model to design time delay compensation vector to constitute the control input, the corresponding Lyapunov function has been structured, to solve the problem of robust stability. In order to solve the problems of the system states that are not fully measurable, a variable substitution method was adopted, which can realize the static output feedback control with reduced dimensions. The Lyapunov theory and linear matrix inequality approaches were used to design the multi-objective cooperative controller, which can be simultaneous improvement in ride comfort and handling stability of the active suspension systems, and take into account constraints such as suspension active control force, tire dynamic deflection and actuator saturation. Finally, the dynamic simulation analysis of the active suspension system under different time-delay conditions verified that the system robust stability and certain performance achieved in the uneven road disturbance. © 2020, Editorial Office of Journal of Vibration and Shock.
