Title:
MAXIMUM TORQUE PER AMPERE CONTROL METHOD AND APPARATUS, TERMINAL DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/257405
Kind Code:
A1
Abstract:
The present application is applicable to the technical field of motor control, and provides a maximum torque per ampere (MTPA) control method and apparatus, a terminal device, and a storage medium. The MTPA control method comprises: acquiring a target signal; injecting the target signal into a first current phase lead angle of a permanent magnet synchronous motor to obtain a second current phase lead angle; determining a first alternating current component and a second alternating current component according to the second current phase lead angle; and adjusting the first current phase lead angle according to the first alternating current component and the second alternating current component, such that the permanent magnet synchronous motor satisfies an MTPA. By means of the present application, the dynamic response speed of MTPA control can be improved, and an MTPA working point can be quickly determined.
