Summary: | The invention discloses a voltage vector selection method and a multi-motor synchronous control system established by the same. The method comprises the following steps: detecting the synchronous error of the multi-motor operation, the stator flux linkage error, the electromagnetic torque error and a sector in which the flux linkage is located, and creating a novel voltage vector switch table suitable for multi-motor synchronous control; and selecting a proper space voltage vector from the novel voltage vector switch table. The system comprises a novel voltage vector switch table-based multi-motor synchronous controller, an inverter, a motor and a flux linkage torque estimation module; and the novel voltage vector switch table-based multi-motor synchronous controller mainly consists of a synchronous error comparison module, a flux linkage comparison module, a torque comparison module and a switch voltage vector module. The invention can well realize the synchronous control performanceand quick response contro |
