Abstract

The embodiments of the invention provide an unmanned aerial vehicle / motor control device and method. The motor control method comprises the following steps: acquiring current attitude information of the load, target attitude information of the load and current operation parameter information of one or more motors on the load, and obtaining control information for controlling the one or more motors according to the current attitude information, the target attitude information and the current operation parameter information; transmitting the control information to a shared memory for storage; and reading the control information from the shared memory and controlling the operation of one or more motors according to the control information. A motor control device according to the invention does not need connection of cables or PCB wiring, thereby reducing hardware size; the motor control device is directly implemented inside a chip through a shared memory, thereby improving the speed and stability of data interaction between a main control unit and an executing unit. Further, a correlation algorithm is adopted for ensuring the no reduction of motor and pan-tilt control frequency and accuracy.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle flight control, in particular, to an unmanned aerial vehicle, a motor control device and a method. Background technique [0002] The gimbal can be coupled with the drone to carry cameras, lights, etc. The pan-tilt is equipped with a motor, and the high-speed attitude of the pan-tilt is realized by the motor, which receives the signal from the controller to run and position accurately. The controller of the motor includes a main control unit and an execution unit. The main control unit is used for the processing of sensor data, as well as functions such as gimbal stabilization and follow-up during the flight of the UAV. The execution unit is used to control the rotation of the motor according to the relevant data of the main control unit. [0003] Such as figure 1 As shown, the solution of the related art is to calculate in real time the motors on the three axes (the first motor...
