Motor drive and flight control method, ESC, power system and UAV system

Abstract

The invention provides a motor drive and flight control method, an ESC, a power system and a UAV system, wherein the UAV system comprises a rack (1), a plurality of power systems (2) respectively arranged on the rack, and Flight controller (200), the power system includes ESC (100) and motor (300), ESC is connected with motor for controlling the working state of the motor; E-communication connection between flight controller and power system; Flight control The device sends the throttle signal to the ESC, and the ESC controls the corresponding motor rotation according to the throttle signal toprovide flight power for the drone, wherein the throttle signal is a differential signal. The invention sends the differential throttle signal to the electric adjustment by the flight controller to drive the motor to rotate, the differential throttle signal has strong anti-interference ability, effectively suppresses electromagnetic interference, and the timing positioning is accurate, so that the ESC can obtain a more accurate throttle signal and realize the motor. The precise control for the precise control of the drone is realized.

Description

technical field [0001] The invention relates to the field of control, in particular to a motor drive and flight control method, an electric regulator, a power system and an unmanned aerial vehicle system. Background technique [0002] In the UAV, the flight controller sends a single-ended throttle signal to the ESC, and the ESC controls the rotation of the corresponding motor according to the received throttle signal, thereby providing flight power for the UAV. [0003] Generally, the frame of the drone includes a central body and arms connected to the central body. Among them, the flight controller is generally set on the center body, and the ESC and motor are set at the end of the arm away from the center body. The single-ended throttle signal sent by the flight controller needs to go through a long transmission path to reach the ESC, while the single-ended The end throttle signal has poor anti-interference, electromagnetic interference suppression, timing positioning, et...

AI Technical Summary

Problems solved by technology

Among them, the flight controller is generally set on the center body, and the ESC and motor are set at the end of the arm away from the center body. The single-ended throttle signal sent by the flight controller needs to go through a long transmission path to reach the ESC, while the single-ended The end throttle signal has poor anti-interference, electromagnetic interference suppression, timing positioning, etc., resulting in poor accuracy of the throttle signal received by the ESC and the inability to accurately control the corresponding motor rotation, thus making it impossible to accurately control the flight of the UAV.
