Guaranteed cost controller design of networked control systems with state delay. (English) Zbl 1153.93378
Summary: This paper is concerned with the state-feedback guaranteed cost controller design for a class of Networked Control Systems (NCSs) with state-delay. A new model of the NCSs is provided under consideration of the network-induced delay. A sufficient condition for the existence of a guaranteed cost controller for NCSs is presented by a set of Linear Matrix Inequalities (LMIs). A method, which can transform non-convex to convex, is applied. Accordingly, a numerical algorithm is proposed to obtain the lower bound. Theoretical analysis through an example shows the effectiveness of the method.
