| description | ObjectivesTo solve the problem of poor synchronization performance and anti-interference ability of dual motor traction mining electric locomotives using permanent magnet synchronous motors （PMSM），Methodsa new dual motor synchronous control method that combines integral sliding mode control with improved cross coupling control was proposed. Firstly，an integral sliding mode controller with a new approach rate was designed to make the system have good speed regulation performance and effectively suppress the chattering phenomenon of sliding mode control. Secondly，a sliding mode disturbance observer was designed to observe and compensate the external disturbances of the motor，so as to improve the system's anti-interference performance. Then，the coupling coefficient in the traditional cross coupling control structure was improved to an adaptive coefficient to alleviate the contradiction between steady-state performance and transient compensation effect. Finally，the new integral sliding mode control and improved cross coupling control structure were combined to build a simulation model of the dual motor synchronous control system for mining electric locomotives. By simulating the possible unexpected situations encountered during the operation of mining electric locomotives，the effectiveness of the proposed dual motor synchronous control method was verified.ResultsWhen the system was subjected to external load disturbances，the motor speed changed little，and the system was not sensitive to the parameter differences between the two motors，which had good anti-interference and robustness. In various emergency situations，the proposed dual motor synchronous control method could maintain good synchronization performance of the system.ConclusionsThe dual motor synchronous control method for mining electric locomotives based on the combination of new integral sliding mode control and improved cross coupling control had good synchronization performance and anti-interference ability，which was of great significance for optimizing the dual motor synchronous control system of mining electric locomotives. |
