Abstract

In this paper a new scheme using model following control is proposed to achieve good robust ride and good robust handling characteristics. To achieve good robust performance, the new state space description is employed in which sprung mass acceleration is contained as a state variable. For the proposed state space description, an adaptive controller is developed to make the state track desired trajectories. To demonstrate usefulness of the proposed adaptive controller, it is shown by numerical simulation results that the proposed active suspension control system has better robust performance than control systems using H infinity controller.
