Nonlinear feedback linearization controller design for half car suspension system

Abstract

This paper investigates the nonlinear controller design of a half car suspension system. The half car suspension system is a multiple-input-multiple-output (MIMO) nonlinear system. The proposed controller design is based on a feedback linearization method. Its prime goal is the coordinated control of ride quality and handling performance which are nowadays challenging for suspension systems, for the applications on unpaved roads. The tracking performance of the proposed control technique in the presence of the deterministic road disturbance has been illustrated using simulation results.
