Title:
MOTOR CONTROL METHOD AND APPARATUS, ELECTRONIC GOVERNOR, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/233021
Kind Code:
A1
Abstract:
A motor control method and apparatus, an electronic governor (20), and an unmanned aerial vehicle (100). The method comprises: acquiring a current battery voltage Udc and a q-axis voltage input instruction value uqref0, and obtaining a current q-axis actual input voltage uqref according the current battery voltage Udc and the q-axis voltage input instruction value uqref0; and controlling a motor (10) according to the current q-axis actual input voltage uqref. According to the control method, the value of a current q-axis actual input voltage uqref is adjusted in real time according to a change in the current battery voltage Udc, the problem of poor control robustness of a motor (10) caused by the fact that a change in voltage of a battery is too large, the control robustness of the motor (10) is improved, and the mobility range of the unmanned aerial vehicle (100) is not affected.
