Title:
GLOBAL CONTROL METHOD AND APPARATUS FOR PERMANENT MAGNET SYNCHRONOUS MOTOR AND PERMANENT MAGNET SYNCHRONOUS MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/002315
Kind Code:
A1
Abstract:
Disclosed in the present application are a global control method and apparatus for a permanent magnet synchronous motor and a permanent magnet synchronous motor. The global control method comprises: acquiring a three-dimensional current pulse spectrum of a non-flux-weakening zone by means of calibration, and acquiring a three-dimensional current pulse spectrum of a flux weakening zone by means of calculation, the three-dimensional current pulse spectrum being a voltage-rotating speed-torque three-dimensional current pulse spectrum; and under a first working condition, according to the three-dimensional current pulse spectrum of the non-flux-weakening zone, using a maximum torque-per-ampere control policy, and under a second working condition, according to the three-dimensional current pulse spectrum of the flux weakening zone, using a maximum torque-per-voltage control policy.
