Decentralized Control Design for Switching Fuzzy Large-Scale T-S Systems by Switched Lyapunov Function with H Performance
Résumé
This paper investigates the H control design for switched fuzzy discrete-time interconnected systems. This type of systems contains nonlinear interconnected subsystems. Every subsystem has different switching modes described by a T-S fuzzy model. Less conservative sufficient conditions are proposed and formulated in terms of LMIs obtained using Switched Lyapunov functions and parallel distributed compensation (PDC) controllers. The design is allowed by H technique and a relaxed method is presented. Two numerical examples are developed to illustrate the effectiveness of the obtained results.
