不确定离散网络控制系统的H∞鲁棒控制

This paper is concerned with an H∞ robust control for a class of Networked Control Systems (NCSs) with uncertain discrete. The NCSs with bounded network-induced and data packet dropout were modeled as closed-loop systems with time-varying input delay. By using a new Lyapunov-Krasovskii function and combining Jessen inequality and reciprocal convex technique, a sufficient condition which asymptotically robust stabilizes closed-loop systems and satisfies H∞ performance index was derived. Compared with the existing literature，This study needs fewer Linear Matrix Inequality(LMI) and matrix variables. Therefore, the result obtained lower conservativeness. Finally, the robust H∞ controller design was obtained with an improved cone complementarity linearization algorithm(ICCL). MATLAB simulation results have shown the effectiveness of the proposed method.
