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.
