Torque Balance of Dual-motor Driven System Based on Equivalent Switching Variable Structure Sliding Mode Control

Focus on the torque balance control of dual-motor driven system (DMDS), this paper proposes an equivalent switching variable structure sliding mode control (VSSMC) algorithm, which can improve the response speed and anti-interference performance of the system. Comparing with the traditional PI control algorithm, the equivalent switching VSSMC can eliminate the steady-state tracking error completely. Based on two control strategies proposed in the previous study, the simulation analysis of the two algorithms is carried out respectively by using MATLAB in this paper, and the effectiveness of equivalent switching VSSMC algorithm is further verified by the simulation results.
