Abstract

The invention provides a regular dodecagon flux linkage track control apparatus and method. The regular dodecagon flux linkage track control apparatus comprises a vehicle-mounted power battery, an auxiliary power supply, a main controller, a driving circuit, a three-phase permanent magnet synchronous motor, a power tube unit, a first relay, a second relay and a third relay. By controlling each switching tube included in the power tube unit through the main controller, flux linkage track control of the three-phase permanent magnet synchronous motor is realized; and in the control process, by controlling each switching tube included in the power tube unit directly, the flux linkage track control of the three-phase permanent magnet synchronous motor is realized, without requiring complex vector conversion and other links, so that the control process is simple, and the response speed of the three-phase permanent magnet synchronous motor is improved.

Description

technical field [0001] The invention relates to electric transmission technology, in particular to a device and method for controlling a regular dodecagonal magnetic chain trajectory. Background technique [0002] With the deepening of the awareness of environmental protection, electric vehicles with the characteristics of zero emission, no pollution, and high energy utilization are more and more favored by consumers. As the power source of electric vehicles, three-phase permanent magnet synchronous motor is one of the important accessories of electric vehicles. [0003] At present, the three-phase windings of the three-phase permanent magnet synchronous motor are respectively connected to the power supply through two switching tubes. In the flux trajectory control process, the voltage space vector control method is used to control the flux trajectory through vector coordinate transformation, current loop control, output coordinate change and other links. [0004] In the a...
