Absrtact: The control mechanism of Dahlin controller is reinterpreted. 　　The incident angle of the root locus of the Dahlin controller is calculated by using the vector analysis method. The relationship between the pole radius and the pole radius of the Dahlin controller and the angle between the positive and real axes is studied. A computer

Three-phase asynchronous motor for pumping unit is a kind of periodic non-uniform load. Because the starting current of the motor is large, and it is mostly in the light load state in the operation process, the waste of electric energy is serious, so it is of great significance to study the energy-saving of pumping unit
