Title:
MOTOR CONTROL METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/210640
Kind Code:
A1
Abstract:
The present application provides a motor control method and apparatus. The method comprises: after an unmanned aerial vehicle takes off, sending a first rotational speed control instruction to a motor which drives a propeller to rotate, the first rotational speed control instruction comprising a first rotational speed acceleration; if it is monitored, when the motor accelerates a rotational speed at the first rotational speed acceleration, that the propeller of the unmanned aerial vehicle is in a low-damping operation state, obtaining the current rotational speed of the motor; determining a second rotational speed acceleration of the motor according to the current rotational speed and the first rotational speed acceleration, the second rotational speed acceleration being greater than the first rotational speed acceleration; and generating a second rotational speed control instruction according to the second rotational speed acceleration, and sending the second rotational speed control instruction to the motor, the second rotational speed control instruction comprising the second rotational speed acceleration. By adjusting the rotational speed acceleration in the rotational speed control instruction of the motor corresponding to the propeller, on the unmanned aerial vehicle, that is in a low-damping operation state, synchronous rotation acceleration of propellers of the unmanned aerial vehicle is implemented, thereby avoiding the problem that an unmanned aerial vehicle is out of balance during an acceleration process.
