  • Abstract In this thesis, robust adaptive fuzzy control and robust adaptive fuzzy sliding mode control schemes are proposed to deal with the tracking control problem of a class of single-input single-output (SISO) nonlinear perturbed strict-feedback systems in the presence of parametric uncertainties. It is well-known that the presence of perturbations is a very common problem in various kinds of engineering systems, and these perturbations involve unmodelled dynamics, external disturbances and time variations. Because of the complexity of structure of the perturbations, the upper bounds of these perturbations are often difficult to be obtained. Therefore, within these above-mentioned approaches, fuzzy logic systems and adaptive laws are applied to approximate the upper bounds of the perturbations. By introducing Lyapunov stability theorem as well as the theory of variable structure control, the robust stability of the overall closed-loop system can be ensured, and good tracking performance can be also obtained at the same time. Finally, two simulation examples are demonstrated to confirm the effectiveness and the feasibility of the proposed control schemes.
