More Information
Summary:A multi-motor synchronous control system comprises a multi-motor synchronous controller based on a novel voltage vector switch list, an inverter, motors and a flux linkage torque estimating module. The multi-motor synchronous controller based on a voltage vector switch list mainly consists of a synchronous error comparison module, a flux linkage comparison module, a torque comparison module and a switch voltage vector module. The multi-motor synchronous control system which adopts a voltage vector selection method and is built according to the same can effectively solve the problems of synchronous control performance and quick response control performance of a multi-motor system, and realizes multi-motor synchronous control based on direct torque control technology by the aid of the controller.
