The invention discloses a pulsator washing machine. The pulsator washing machine comprises a box body, an inner barrel, an outer barrel, an impeller structure, a power-driven system and a control device. The impeller structure comprises a first impeller and a second impeller. The power-driven system comprises a double-rotor motor, a first controller and a second controller. The double-rotor motor comprises a stator, a first rotor and a second rotor. The first rotor is connected with the first impeller, the second rotor is connected with the second impeller, and the first controller and the second controller are in data interaction. The control device determines a clothes washing mode according to user instructions, and generates control signals according to the clothes washing mode. The first controller controls the first rotor according to the control signals so as to adjust the rotating speed and direction of the first impeller, and the second controller controls the second rotor according to the control signals and the interaction data so as to adjust the rotating speed and direction of the second impeller. According to the pulsator washing machine, a varied and powerful washing water flow effect can be achieved. The invention further discloses a control method and the power-driven system of the pulsator washing machine.
