Robust Dynamic Output Feedback Sliding-Mode Control of Singular Perturbation Systems

Abstract

In this paper, the design of the robust dynamic output feedback sliding-mode controller (SMC) for singular perturbation systems is investigated. All the gain matrices of the dynamic sliding-mode controller can be determined via the static output feedback control for the alternative model of the reduced sliding dynamics. The results obtained differ from those of Refs. (6), (7) and (13) with respect to dynamic output feedback and also from those of Ref. (31) with respect to sliding-mode control. An active suspension system for a quarter-car is exploited to illustrate the derived schemes.
