Control of Fuzzy Switched Time-Delay Uncertain Systems: An Improved Robust Output Feedback Design

AbstractRobust output feedback control for a class of switched uncertain time-delay fuzzy systems via both methods with common Lyapunov and multiple Lyapunov functions is studied in this paper. Using Parallel Distributed Compensation, observer estimators and a switching law, the fuzzy output feedback controllers are designed such that the corresponding closed-loop system possesses robustness for all admissible uncertainties. The solution inequalities are expressed in LMI. An illustrative example along with the respective simulation results is given to demonstrate the effectiveness of the proposed design.
