The invention provides a multi-point cooperative suspension control system of a suspended maglev train. The system comprises a pressure sensor, a vehicle-mounted master control system, a suspension controller and four groups of execution units. Each group of execution units comprises a vehicle-mounted suspension device, a suspension chopper, an acceleration sensor, a gap sensor and a current sensor. The vehicle-mounted suspension device comprises an electromagnetic regulation module and a permanent magnet module; The main levitation force is provided by the repulsive force generated by the vehicle-mounted levitation device and the permanent magnet rail. The function of the electromagnetic regulation module of the vehicle-mounted levitation device is to assist the levitation device to increase damping, eliminate vibration, and realize the electric decoupling control to make the train levitation stably in the rated levitation gap.
