Title:
DUAL THREE-PHASE PERMANENT MAGNET SYNCHRONOUS MOTOR CONTROL METHOD FOR ALTERNATELY EXECUTING SAMPLING AND CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/151609
Kind Code:
A1
Abstract:
The present invention relates to the technical field of power generation, power transformation, or power distribution, and disclosed in the present invention is a dual three-phase permanent magnet synchronous motor control method for alternately executing sampling and a control program. Sampling moments, loading vector moments, and reference value tracking moments of two windings of a motor are mutually alternated for half a sampling period, such that the present invention enables the equivalent sampling frequency of a motor control system to be doubled and the control delay and the prediction time span to be halved without changing the sampling frequency of a single three-phase winding. In addition, the present invention solves, by means of a double-layer model prediction control strategy, the underactuation problem that the controlled dimension of a system is reduced to two dimensions but a control target is still four-dimensional due to the dual three-phase permanent magnet synchronous motor control method for alternately executing sampling and the control program. The dual three-phase permanent magnet synchronous motor control method for alternately executing sampling and the control program provided by the present invention effectively improves the steady-state and dynamic control performance of a dual three-phase permanent magnet synchronous motor system, and reduces the calculation amount of a control algorithm.
