Title: METHOD, DEVICE AND SYSTEM FOR CONTROLLING MOTOR
Abstract:
A method, device and system for controlling a motor (22). The method comprises: obtaining a current electrical parameter of a battery (20) (S101); calculating a compensation amount of a control signal of a motor (22) according to the current electrical parameter (S102); and correcting the control signal of the motor (22) according to the compensation amount of the control signal (S103). By means of the method, the fluctuation of control signals of a motor (22) as electrical parameters of a battery (20) change is avoided, and difference of control signals of the motor (22) under the control of a same accelerator signal is avoided, accordingly the problem of slow response usually occurring when an unmanned aerial vehicle needs to perform some actions requiring high maneuverability, and the phenomenon of increasing lack of power as the process of the flight of the unmanned aerial vehicle goes is avoided.
