Decentralized Robust Control for Large Scale Interconnected Uncertain Systems with Time Delay-LMI Approach
不确定性关联时滞大系统的分散鲁棒控制——LMI方法

For a class of interconnected time delay uncertain systems, which satisfy the matching conditions, a sufficient condition for decentralized stabilization feedback control laws is derived based on Lyapunov stability theorem. This condition is expressed as the solvability problem of linear matrix inequalities. Based on that, a convex optimization problem with LMI constraints is formulated to design a decentralized state feedback control with smaller gain parameters which enables the closed loop system asymptotically stable. The given examples show the application and the superiority of the method.
