Abstract

The purpose of the paper is to study the design of the active wheel suspension system. The goal of the control design is the disturbance attenuation with respect to the road disturbances when some of the physical parameters of the system are uncertain. On the basis of a linear quarter-car model the tire stiffness and suspension stiffness are assumed to be uncertain. In this paper the authors deal with some new robust design methods. They examine the applicability of H control in case of the active suspension system using a quarter-car model. The problem is solved as a direct state-feedback H control problem and in case of structured uncertainties as an RLQR (Robust LQR) design task. On the basis of combination of these two methods new procedure is proposed.
