The invention discloses a traction and suspension combined control method for an embedded maglev train. The method comprises the steps that a traction sensor detects the speed v of a motor, the primary phase current i of the motor and the primary electric frequency omega s of the motor in real time; a suspension gap sensor detects a suspension air gap g in real time, namely a motor air gap; the suspension air gap g is input into the traction inverter; the traction inverter establishes a real-time linear motor model according to the received motor air gap value; the motor speed v, the motor primary phase current i and the motor primary electric frequency omega s are input into the suspension controller, and the suspension controller calculates the normal force Fy of the linear motor according to the received motor speed v, the motor primary phase current i, the motor primary current frequency omega s and the motor air gap g. According to the method, data of the suspension system and the traction system are fused, interference between the suspension system and the traction system is restrained, the suspension stability is improved, the traction performance is improved, and optimization of the suspension performance and the traction performance is achieved.
