H∞ Controller Design Based on Redundant Channel Scheme for Networked T-S Fuzzy Systems

摘要

This paper is concerned with the H_∞ controller design problem for a class of networked nonlinear systems represented by the Takagi-Sugeno (T-S) fuzzy model. The data packets will unavoidable be lost during the transmission due to the network congestion. In order to improve the reliability of communication, a scheme of sensors equipped with redundant channels is proposed to reduce the negative effect of packet dropouts. Sufficient conditions on the existence of the desired controller are established by employing Lyapunov stability theory to ensure that the resulting closed-loop system is stochastically stable and achieves a prescribed H_∞ performance index. An example is utilized to illustrate the effectiveness of the proposed algorithm.
