为了提升大功率牵引电机定速控制精度，提出了一种模糊自适应控制方法。根据外部条件的变化，利用输入输出的模糊关系来自适应调节给定牵引/制动力矩，采用Butterworth滤波器对输出给定力矩进行滤波并利用积分环节来消除稳态误差，以获得良好的控制性能。以某型机车大功率牵引电机为测试对象，对各种复杂运用工况算法控制效果进行对比仿真测试，验证了所提算法的有效性和优越性。

In order to improve the speed control accuracy of high power traction motor, a fuzzy adaptive control method is proposed. According to the change of external conditions, the fuzzy relationship between input and output is used to adjust the given traction/braking torque adaptively, and then the Butterworth filter is used to filter the output given torque and the integral link is used to eliminate the steady state error to obtain good control performance. Finally, taking a high power traction motor of a locomotive as the test object, the control effect tests of various complex operation conditions are carried out, and the effectiveness and superiority of the proposed algorithm are verified.
