Abstract :
This paper focuses on the problem of stability analysis and control synthesis for nonlinear systems with variable sampling based on Takagi-Sugeno(T-S) fuzzy model approach. A novel piecewise Lyapunov-Krasovskii functional is constructed for stability analysis and controller design. Based on the feasibility of a set of linear matrix inequalities (LMIs), the sufficient conditions of stabilization via sampled-data feedback are proposed. Numerical example demonstrates the effectiveness of our results.
