The invention discloses a washing machine and a control system and control method thereof. The control system comprises a human body infrared detection device, a signal processing module, a main control panel and a voice module. The human body infrared detection device detects whether a user is close to the washing machine or not so as to generate a human body detection signal; the signal processing module is used for conducting interference removing processing on the human body detection signal; the main control panel is connected to the signal processing module, and controls the washing machine to be electrified when the user is judged to be close to the washing machine according to the processed human body detection signal; when the washing machine executes a washing program, the main control panel further controls the voice module to broadcast running state information of the washing machine. In this way, the control system can control the washing machine to be electrified when the user is close to the washing machine, thus the automatic wakening function of the washing machine is achieved, the electric energy is saved, and the trouble that the user repeatedly unplugs the plug is solved at the same time; moreover, the running state information of the washing machine can be broadcast when the washing machine executes the washing program, and brand new interaction between the user and the washing machine is achieved.
