Abstract: Due to simple structure features, low cost, small starting current, large starting torque, and reliability, Switched Reluctance Motor (SRM) are very suitable for application in the mine electric locomotive electric transmission system. The basic structure and working principle of SRM were introduced, considering the working characteristics of mine electric locomotive, direct torque control strategy based on adaptive fuzzy PI control was proposed. Design method of the strategy was elaborated, after which simulation verification of control effect and comparison analysis with traditional methods were conducted. Simulation results show that, the control strategy effectively solves the problem of large torque ripple and significantly improves system dynamic performance, which is obviously valuable for application.

Key words: mine electric locomotive, switched reluctance motor, adaptive fuzzy PI control, direct torque control, simulation
