Robust Fuzzy H∞ Output Feedback Control for a Class of Nonlinear Uncertain Systems with Mixed Time Delays

Abstract EN

This paper studies the problem of delay-dependent robust H∞ output feedback control for a class of uncertain fuzzy neutral systems with both discrete and distributed delays.

The system is described by a state-space Takagi-Sugeno fuzzy model with distributed delays and norm-bounded parameter uncertainties.

The purpose is to design a fuzzy dynamic output feedback controller which ensures the robust asymptoticstability of the closed-loop fuzzy neutral system and satisfies an H∞ norm bound constraint for all admissible uncertainties.

In terms of linear matrix inequalities, sufficient conditions for the solvability of this problem are presented.

Finally, a numerical example is included to demonstrate the effectiveness of the proposed method.
