Embodiment 1

[0059] see figure 2 , the motor driving method may include the following steps:

[0060] Step S201: receiving the throttle signal sent by the flight controller 200, wherein the throttle signal is a differential signal;

[0061] Wherein, the accelerator signal may include operating parameters required for driving the motor 300 such as the motor speed and the direction of rotation of the motor. In this embodiment, the differential accelerator signal is composed of two level signals with equal amplitude and opposite polarity, and the ESC 100 can receive two level signals with equal amplitude and opposite polarity at the same time, and The received two level signals are used to control the rotation of the corresponding motor 300 (that is, the motor 300 connected to the ESC 100 ).

[0062] Step S202: Control the motor 300 to rotate according to the throttle signal.

[0063] After step S201, the ESC 100 that receives the throttle signal will immediately execute step S202, so as ...

Embodiment 2

[0074] see Figure 4 , the flight control method may include the following steps:

Wherein, the device for remote control of the drone may be a drone remote control or a device installed with APP (application software).

[0077] In some embodiments, the user instruction includes at least one of motor speed and motor direction, so as to control the motor 300 to rotate at a specific speed, and to control the motor 300 to rotate clockwise or counterclockwise to meet a specific power requirement. Of course, in other embodiments, the user instruction may also include signals of other motor operating parameters, for example, motor operating temperature, vibration magnitude and so on.

[0078] Step S402: Generate ...

Embodiment 3

[0085] see Figure 5 , an embodiment of the present invention provides a motor driving system, and the motor driving system may include a first processor 101 . Wherein, the first processor 101 is communicatively connected with the corresponding motor 300 for controlling the working state of the corresponding motor 300 or receiving information fed back by the corresponding motor 300 .

[0086] In this embodiment, the first processor 101 includes one or more, working individually or jointly, for executing the steps of the motor driving method described in the first embodiment above.

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...
