网络化离散时滞系统的鲁棒输出反馈控制
Robust Output-feedback Control for Networked Discrete Time-delay Systems
摘要
Abstract
In this paper, the robust output-feedback control problem is considered for polytopic discrete-time systems with delay in network environments. It is assumed that there exist unreliable communication links between the controller and the actuator. Multiple independent random variables are adopted to characterize the data-missing phenomenon in multicommunication channels. The robust stochastic stability is first analyzed based on a parameter-dependent Lyapunov-Krasovskii functional. Then,the problem of the parameter-dependent robust output-feedback controller design is formulated as the convex optimization problem of solving a set of linear matrix inequalities. Finally, a simulation example is provided to show the effectiveness of the proposed method.关键词
