Embodiment Construction

[0036] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] As the core control device for aerial photography, monitoring, remote sensing, and sampling pan-tilt, the driving control system for stabilizing the pan-tilt can work under the working conditions that the stable frame of the stabilizing pan-tilt generates angular motion, such as the pan-tilt hanging on the drone , the flight attitude of the UAV changes, and by controlling the rotation of the brushless motors of each axis of the stabilized platform, it is ensured that the pointing angle of the imaging device carried on the stabilized platform is always inertially stable or always points to the target of interest.

[0038] The present invention provides a drive control system for a brushless motor in an embodiment, such as figure 1 As shown, the drive control system includes a stable level digital control system 1 connected to at least ...

Abstract

The invention relate to a vector control method for controlling motor rotation. The vector control method comprises the following steps of judging whether an electrical angle absolute initial value exists or not; if the electrical angle absolute initial value does not exist, obtaining a current electrical angle value, a quadrature-axis voltage control quantity, a direct-axis voltage control quantity, and an electrical angle absolute initial value at the initial mode; if the electrical angle absolute initial value exists, obtaining an angle value of an absolute angle position sensor, and obtaining the current electrical angle value according to the angle value of the absolute angle position sensor and the electrical angle absolute initial value; and obtaining the duty ratio of output PWM according to the current electrical angle value, the quadrature-axis voltage control quantity and the direct-axis voltage control quantity, so as to control rotation of the motor.

Description

technical field [0001] The invention relates to the technical field of stabilized pan-tilts, in particular to a vector control method and control system for controlling motor rotation and a stabilized pan-tilt. Background technique [0002] In recent years, all kinds of moving base imaging gimbals have been widely used in aerial photography, unmanned vehicles, robots and other fields, and have attracted more and more attention. In particular, the use of drones for aerial photography is an important means to quickly, flexibly, clearly and accurately obtain photos and video information of areas of interest to people. However, for the mobile base carrier represented by drones, there are inevitably changes in the carrier's attitude, vibration and other influences during the movement process, resulting in severe shaking of the video and blurred photos. The birth of the stable gimbal solves this problem. The stabilized gimbal consists of a multi-degree-of-freedom mechanical mech...
