An intelligent cooperative control system and method thereof. A parallel structure for low-voltage multi-module permanent magnet synchronous motor cooperative control units is adopted to realize control of low-voltage high power, control of low-speed large torque and system redundancy control; a double-parallel PWM rectifier circuit structure is used, when the system is in unbalanced power supply network environments; a resonant pole-type three-phase soft-switching inverter circuit is used as an inverter unit to improve utilization of DC bus voltage and to greatly reduce device switch losses at high frequencies; a current control and speed estimation unit is used, so that rotor speed and phase angle information is accurately estimated with low cost and high reliability; a controlled object is the multi-module permanent magnet synchronous motor, so that the problems of difficulties in motor installation, transportation and maintenance of a high-power electric drive system and the like are solved.
An intelligent cooperative control system for a multi-unit permanent magnet synchronous motor, comprising a double-parallel PWM rectifier circuit, a first permanent magnet motor cooperative control unit, a second permanent magnet motor cooperative control unit, a third permanent magnet motor cooperative control unit and a multi-unit permanent magnet synchronous motor, wherein the first permanent magnet motor cooperative control unit, the second permanent magnet motor cooperative control unit and the third permanent magnet motor cooperative control unit cooperatively control three stator units of the multi-unit permanent magnet synchronous motor in a parallel connection manner.
