Robust H2 and H∞ Control of Discrete-time Systems with Polytopic Uncertainties via Dynamic Output Feedback

This paper addresses the problem of robust H2 and H∞ control of discrete linear time-invariant (LTI) systems with polytopic uncertainties via dynamic output feedback. The problem has been known to be difficult when a parameter dependent Lyapunov function is to be applied for a less conservative design due to non-convexity. Our approach is based on a novel bounding technique that converts the no...

Robust output feedback stabilization of a class of time-varying non-linear systems

This paper deals with the problem of robust output feedback stabilization of a class of time-varying non-linear systems. This class of systems involves two kinds of timevarying uncertainties: those norm-bounded and those bounded by a smooth non-linear function of the output. Under the assumption that the zero dynamics of the system are uniformly asymptotically stable and some additional mild co...

Robust ∞ H Control of Switched Uncertain Time-varying Delay Discrete-time Systems via Dynamic Output Feedback

Robust H output feedback control problem for a class of switched linear discrete-time systems possessing normbounded uncertainty and time-varying delay is investigated. A switched dynamic output feedback controller is sought that can robust exponentially stabilize and reduce to a prescribed level the effect of disturbance input on the controlled output in the closed loop. A delay depen dent lin...

Robust output feedback stabilization via risk-sensitive control

We consider a problem of robust linear quadratic Gaussian (LQG) control for discrete-time stochastic uncertain systems with partial state measurements. For a 6nite-horizon case, the problem was recently introduced by Petersen et al. (IEEE Trans. Automat. Control 45 (2000) 398). In this paper, an in6nite horizon extension of the results of Petersen et al. (IEEE Trans. Automat. Control 45 (2000) ...
