摘      要：The harsh operating environment and complex operating conditions of the mine electric locomotive affect the control performance of the locomotive traction *** order to improve the speed control performance of electric locomotive traction motors,a dynamic fractional-order sliding mode control(DFOSMC)algorithm considering uncertain factors was proposed.A load torque sliding mode observer was designed for the complex load disturbance of the traction motor,and its observations were integrated into the DFOSMC controller to overcome the influence of load ***,the stability of the designed controller was proved by Lyapunov s ***,the control performance of DFOSMC controller was compared with integer-order sliding mode controller and fractional-order sliding mode controller through simulation *** with integer-order sliding mode and fractional-order sliding mode controllers,the dynamic and static performance of the DFOSMC controller with load observation is better,and it has stronger anti-interference *** DFOSMC controller effectively improves the control performance of the traction motor of the mining locomotive.

主 题 词：mine electric locomotive fractional-order sliding mode load observer dynamic fractional-order sliding mode control(DFOSMC)
