The invention provides a control system for a resonant mixer. The control system comprises a controller, an operation board card, servo motor drive units and an acceleration sensor. The servo motor drive units are connected with servo motors of the resonant mixer. The acceleration sensor is placed at a load end of the resonant mixer. The servo motor drive units are used for sending states and angle values of the servo motors to the controller and controlling the servo motor to rotate according to control signals fed back by the controller. The controller is used for sending the states and angle values of the servo motors sent by the servo motor drive units and load acceleration measured by the acceleration sensor to the operation board card, generating the control signals according to motor angles and acceleration computed by the operation board card and sending the control signals to the servo motor drive units. According to the resonant mixer, in a mode of automatic control and keeping a material in a whole load container at a resonant state, the efficient, rapid and uniform mixing purpose with the lowest power consumption is achieved.
