Optimal Tracking Control for a Class of Large-Scale Interconnected system with Time-varying Delay

This paper is concerned with the design problem of the optimal tracking controller design problem for a class of large-scale interconnected systems with time-varying delay. In terms of the feasible solutions to LMIs, a sufficient condition is derived for the existence of optimal tracking controller for a class of large-scale interconnected systems with time-varying delay. The design problem of the optimal tracking controller is formulated as a convex optimization problem. Furthermore, an example is given to illustrate the effectiveness of the conclusion.
