Guaranteed cost control for the discrete time singular interval systems
离散广义区间系统的保成本控制

The problem of guaranteed cost control for the discrete-time singular interval systems was analyzed.When the system parameters vary within a certain interval matrices,the stability of closed-loop system and a certain upper bound of the linear quadratic cost function are both guaranteed by the controller.Based on Lyapunov stability theory,the design of controller can be transformed to a linear matrix inequality (LMI) feasibility problem.The numerical simulation result was provided to demonstrate the effectiveness of the presented method.
