The invention relates to the technical field of alternating-current asynchronous motor control, and particularly relates to an artificial bee colony parameter optimization-based direct torque controlmethod for an alternating-current asynchronous motor slip film variable structure. The artificial bee colony parameter optimization-based direct torque control method for the alternating-current asynchronous motor slip film variable structure specifically comprises the following steps of establishing a stator flux linkage equation, an electromagnetic torque equation and a magnetic chain amplitudesquare expression of an alternating-current asynchronous motor; establishing a direct torque controller equation of the slip film variable structure; designing a calculation method for calculating thetarget function and the fitness value of an artificial bee colony optimization algorithm; initializing a nectar source position of a standard artificial bee colony algorithm; and finally, determiningthe parameters of a slide film variable structure controller equation through the search of the standard artificial bee colony. According to the method, a torque and magnetic chain slip film variablestructure-based controller is designed to replace a traditional direct torque controller. Meanwhile, the optimal parameters of the slip film variable structure-based controller are determined throughthe search of the artificial bee colony. Therefore, the variable-frequency speed regulation performance of the alternating-current asynchronous motor is effectively improved.
