Abstract

In this paper the design problem is addressed for linear discrete-time systems with state variables equality constraints. Based on an equivalent linear matrix inequality representation of bounded real lemma for discrete-time systems a new formulation is provided for the control law gain computation to circumvent a generally ill conditioned singular design task. The approach is successfully illustrated on a simulation example, where validity of the proposed method is demonstrated.

H∞ control of discrete-time linear systems constrained in state by equality constraints

AbstractIn this paper, stabilizing problems in control design are addressed for linear discrete-time systems, reflecting equality constraints tying together some state variables. Based on an enhanced representation of the bounded real lemma for ...
Delay-dependent robust H_∞ control for uncertain discrete-time fuzzy systems with time-varying delays

This paper deals with the robust H_∞ control problem for discrete-time Takagi-Sugeno (T-S) fuzzy systems with norm-bounded parametric uncertainties and interval time-varying delays. First, based on a new Lyapunov functional, we present a sufficient ...
