Abstract

This paper investigates an application of additive control gain to the guaranteed cost control problem of decentralized robust control for a class of discrete-time uncertain large-scale systems. Based on Linear Matrix Inequality (LMI) design approach, a class of decentralized local fixed state feedback controllers with the additive control gain is established. The novel contribution of this paper is that the multi objective control is attained by using the additive control gain. Although the additive control gain is included in the uncertain large-scale systems, the closed-loop system is asymptotically stable. In order to demonstrate the efficiency of our proposed controller, using the fuzzy logic control as the additive control gain, the simple numerical example is given.
