Backstepping-based optimal control design of hydraulic active suspension applied to a full-car model
基于Backstepping 方法的全车液压主动悬挂最优控制设计

It is a main way to improve the performance of the cars by designing advanced suspension systems. The detailed seven degrees-of-freedom nonlinear model of full-car parallel hydraulic active suspension is built. A new active suspension control strategy using the combination of optimal control and backstepping technique is presented based on the system structure characteristic. Simulation results are also given to demonstrate that the control strategy is effective, and the performance of the active suspension is obviously superior to the passive suspension in the same condition.
