Title:
METHOD AND DEVICE FOR CONTROLLING ACCELERATION OF MOTOR OF UNMANNED AERIAL VEHICLE AND ELECTRONIC SPEED CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2019/223211
Kind Code:
A1
Abstract:
The problem in the prior art that the active voltage decreases continuously when a vehicle arm is abnormal is solved; the situation that the unmanned aerial vehicle (100) falls down in one direction is effectively avoided; and the power of the unmanned aerial vehicle (100) is guaranteed to be sufficient such that the unmanned aerial vehicle can make a return voyage or can fly to other safety places. The method comprises: obtaining operating parameters of the unmanned aerial vehicle (100)(101); determining, according to the operating parameters, whether the vehicle arm of the unmanned aerial vehicle (100) is abnormal and whether the unmanned aerial vehicle is in a flight state (102); if the vehicle arm of the unmanned aerial vehicle (100) is abnormal and the unmanned aerial vehicle is in a flight state, increasing the q-axis voltage U qref of the last moment or maintaining the q-axis voltage U qref of the last moment unchanged so as to obtain the q-axis voltage U' qref of the current moment (103); and controlling the motor (10) according to the q-axis voltage U' qref of the current moment (104).
