Title:
MOTOR ACCELERATION METHOD AND APPARATUS, AND ELECTRONIC SPEED REGULATOR AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/196352
Kind Code:
A1
Abstract:
A motor acceleration method and apparatus, and an unmanned aerial vehicle. The method comprises: performing closed loop control on a d-axis current to obtain a current d-axis voltage; determining a q-axis voltage change coefficient K, wherein when the current peak value is greater than a preset current threshold, K is less than or equal to 0, and when the current peak value is less than or equal to the preset current threshold, K is greater than 0; obtaining a current q-axis voltage U'qref according to a formula U'qref = Uqref + KΔUqref, wherein Uqref represents the q-axis voltage of the last moment, and the ΔUqref represents the preset q-axis voltage change value; and performing motor control according to the current d-axis voltage and the current q-axis voltage.
