CONTROL METHOD AND APPARATUS, AND STORAGE MEDIUM

WIPO Patent Application WO/2024/051227

A1

Disclosed in the embodiments of the present application is a control method. The method is used for controlling a BLDCM. A driving circuit of the BLDCM comprises a DC-DC converter and a three-phase inverter. The method comprises: acquiring a target value of a parameter to be controlled of a BLDCM; on the basis of the target value, adjusting both the current duty ratio of a DC-DC converter and the current turning-on length of a switch tube of a three-phase inverter, so as to obtain a target duty ratio of the DC-DC converter and a target turning-on length of the switch tube in the three-phase inverter, wherein the current turning-on length and the target turning-on length are turning-on lengths with respect to an electrical angle of the BLDCM; and controlling the DC-DC converter on the basis of the target duty ratio, and controlling the three-phase inverter on the basis of the target turning-on length, so as to drive the BLDCM. Further disclosed in the embodiments of the present application are a control apparatus and a storage medium.
