The adaptive variable proportional gain fuzzy tracking control design problem for a class of strict-feedback systems with unknown uncertain functions and unknown external disturbances is investigated in this paper. Fuzzy logic systems(FLSs) are introduced to identify the unknown function. What's more, the approximation error and unknown external disturbance of the fuzzy logic system are defined as the total disturbance, and the accurate differential observer is used to perform accurate differential compensation control. By introducing a nonlinear function to design the adjustable output feedback gain, the steady-state error of the system is reduced. So that the output tracking error of the system can be reduced arbitrarily small. Finally, the stability of the fuzzy control systems is proved based on the common Lyapunov function method. The numerical simulation examples are presented to further demonstrate the effectiveness of the proposed control strategies.
