Abstract

Proposes a model-reference sliding mode controller for multivariable systems with relative degree one. The closed loop system is shown to be exponentially stable. The only required apriori information about the high frequency gain matrix K_p of the plant is the knowledge of a matrix S_p such that -K_pS_p is Hurwitz. This relaxes the positive definiteness requirement usually needed by other methods
