Abstract :
This paper presents a intelligent digital redesign technique for the fuzzy dynamic output-feedback controller of the nonlinear system. A Takagi-Sugeno fuzzy model is adopted for the nonlinear system and the discretized models of the analog and digital closed-loop system with fuzzy dynamic output-feedback controllers, respectively. Sufficient conditions are derived for both the stabilization of the digital closed-loop system and minimization of the matrix norm distance between the analog and digital closed-loop system matrices. Its sufficient conditions are formulated in terms of linear matrix inequalities. Finally, a numerical example is provided to verify the effectiveness of the proposed technique.
