Embodiment Construction

[0064] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", and "bottom" used in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the The invention and the simplified description do not indicate or imply that the device or element referred to must have a specific orientation...

Abstract

The invention relates to a motor control method, a motor control device and an unmanned aerial vehicle control system. The motor control method includes: receiving a control signal for controlling the motor speed; obtaining an upper limit threshold of a given signal of the motor under the current voltage; when the received given signal is smaller than the upper limit threshold of the given signal, using the The received given signal is used as a given value for motor control to output a control signal corresponding to the given value to the motor; when the received given signal is greater than the given signal upper threshold, the given signal is used The signal upper threshold is used as a given value for motor control, and a control signal corresponding to the given value is output to the motor. It combines the robustness of motor control for adjustment and control, and adjusts the step process of the control signal by calculating the step limit of the motor to avoid the problem of motor runaway caused by excessive single adjustment range.

Description

【Technical field】 [0001] The invention relates to the technical field of motor control, in particular to a motor control method, a motor control device and an unmanned aerial vehicle control system. 【Background technique】 [0002] In order to realize the controllability of the machine, many motor control methods or control systems based on different strategies are currently provided for the user to input corresponding control signals to adjust the operation of the motor to perform corresponding actions. [0003] For example, in the process of controlling the UAV, as a controlled aerial vehicle, the user usually sends corresponding operation instructions to the UAV through the remote control to control it to operate in various attitudes. After the remote controller receives the operation instruction, the UAV control system will convert the operation instruction into the corresponding motor control signal. These motor control signals are respectively transmitted to the ESC co...
