Observer and Controller Design for Half-Car Active Suspension System Using Singular Perturbation Theory

Abstract:

In this paper the singular perturbation theory is used to design observer for estimation of state variables for proper control of half-car active suspension system. The liner quadric Gaussian (LQG) controller has been used to obtain feedback gains. The suspension system performance is optimized with respect to ride comfort, tire deflections and front and rear suspension travels. The simulation results show that the proposed approach is highly effective in evaluating the performance of an active suspension system.
