In this paper, we propose an adaptive control scheme for a class of nonlinear time-delay systems. To alleviate the requirement for accurate modeling of the plant, a two-level robust control scheme was proposed. The inner-level adaptive neural controller is responsible for accurate servo control, while the outer-level supervising controller compensates for un-modeled system dynamics and bounded disturbances...
This paper investigates the problem of delay dependent robust stability analysis and Hinfin filtering design for a class of uncertain continuous-time nonlinear systems with time-varying state delay represented by T-S fuzzy models. Based on a newly developed Lyapunov-Krasovskii functional combined with an improved free-weighting matrix technique, a new sufficient condition for robust stability analysis...
The problem of fuzzy modeling for state and input time-varying delay systems with a class of nonlinear uncertainties by fuzzy T-S model is addressed. Utilizing LMI (linear matrix inequality), the problem of fuzzy robust Hinfin controller design for the systems is studied. Assuming that the nonlinear uncertain functions in the model considered are gain-bounded, we obtain a sufficient condition for...
