This paper describes a method for designing discrete time static output feedback sliding mode controllers. Previous work has shown that by identifying a minimal set of current and past outputs, an augmented system can be obtained which permits the design of a sliding surface based upon output information only, if the invariant zeros of this augmented system(More)
This paper considers the problem of designing an output feedback sliding mode controller for discrete time systems. A minimal set of current and past outputs are identified to determine an extended output signal. This augmented system permits the design of a sliding manifold based upon output information only, which renders the sliding mode dynamics stable.(More)
This paper discusses the design of a static output feedback based sliding mode controller for MIMO nonminimum phase discrete time systems. In previous work, it was shown that by identifying a minimal set of current and past outputs to determine an extended output signal, an augmented system can be obtained which permits the design of a sliding manifold(More)
This paper describes a method for designing discrete time static output feedback sliding mode tracking controllers for uncertain systems that are not necessarily minimum phase or of relative degree one. In this work, a procedure for realizing discrete time controllers via a particular set of extended outputs is presented for systems with uncertainties. The(More)
