摘要：

This study investigates a finite-time fault-tolerant control scheme for a class of non-affine nonlinear system with actuator faults and unknown disturbances. A global approximation method is applied to non-affine nonlinear system to convert it into an affine-like expression with accuracy. An adaptive terminal sliding mode disturbance observer is proposed to estimate unknown compound disturbances in finite time, including external disturbances and system uncertainties, which enhances system robustness. Controllers based on finite-time Lyapunov theory are designed to force tracking errors to zero in finite time. Simulation results demonstrate the effectiveness of proposed method.
