In this paper, a novel fast recursive dynamic sliding control method based on extended state observer is proposed for dual-motor servo system with backlash nonlinearity. The extended state observer is improved by introducing a new nonlinear function to avoid high-frequency oscillation and simplify the designing process. Then, a fast recursive dynamic sliding controller is designed, which can make...
This paper proposes a fast terminal sliding mode synchronization (FTSMS) control with variable coefficient for dual-motor driving servo systems with unknown backlash. The proposed algorithm consists of two parts, the dual-motor synchronization control and the load tracking control. A nonlinear variable coefficient characterizing the synchronization rate is used for fast terminal sliding mode, such...
