Decentralized Control Design for Switching Fuzzy Large-Scale T–S Systems by Switched Lyapunov Function with $$H_\infty $$H∞ Performance

AbstractThis paper investigates the $$H_{\infty }$$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 $$H_{\infty }$$H∞ technique and a relaxed method is presented. Two numerical examples are developed to illustrate the effectiveness of the obtained results.
