Abstract
⺠A Takagi-Sugeno (T-S) fuzzy model represents the nonlinear system with time-varying delay. ⺠A fuzzy observer design estimates immeasurable state. ⺠Third, a virtual desired variable (VDV) based tracking controller design guarantees Hâ control performance for the overall system. ⺠Using Lyapunov-Krasovskii's stability analysis, we obtain sufficient conditions for stability of estimation, control, and robustness. ⺠We allow unknown time-varying delay, ensure robust output tracking, provide relaxed conditions via a three-steps procedure to find observer and controller gain.
