Abstract :
Aiming at the problem that common sliding mode control method can not satisfy the control need of nonlinear system with disturbances and uncertainties, this paper proposed a modified global fast terminal sliding mode control method with time-delay estimation (TDE), through which, the disturbances and uncertainties were estimated and simulation analysis was carried on the brushless DC motor actuator. The results of the simulation indicate that the modified method proposed in this paper has good control effect. Also, its requirement for system model is simple and has high position tracking precision.
