Asynchronous Decentralized Fuzzy Observer-Based Output Feedback Control of Nonlinear Large-Scale Systems

This paper is concerned with the problem of decentralized robust H_∞ output feedback control for a class of continuous-time nonlinear large-scale systems based on T–S fuzzy affine models. Based on a common quadratic Lyapunov function and piecewise quadratic Lyapunov functions, some new results are proposed to the asynchronous observer-based controller synthesis for T–S fuzzy affine large-scale systems with unmeasurable premise variables. The observer and controller gains can be attained through solving a set of linear matrix inequalities. Finally, two simulation examples are presented to verify the effectiveness of the proposed approaches.
