Three-axis stable pan-tilt

Abstract

The invention relates to a three-axis stable pan-tilt. The three-axis stable pan-tilt comprises a base, wherein a yaw axis control brushless motor is arranged on the base and connected with a roll axis control brushless motor through an inter-axis connection support I; the roll axis control brushless motor is connected with a pitching axis control brushless motor through an inter-axis connection support II; an equipment fixing platform is arranged on a rotor of the pitching axis control brushless motor; a feedback control module is arranged on the equipment fixing platform; and a master control module is arranged on the base. The three small-sized DC brushless motors in orthogonal connection are adopted to adjust the stability of three axes of the pan-tilt, feed-forward and feedback composite control is utilized to realize stable feedback control and rapid feed-forward control and can guarantee that the pan-tilt system is more stable, and the three-axis stable pan-tilt is stronger in controllability and is suitable for popularization and practical application.

Description

technical field [0001] The patent of the present invention relates to a three-axis stable cloud platform, specifically a controllable handheld shooting and monitoring application, capable of stable shooting, and a three-degree-of-freedom shooting cloud for loading mobile phones and cameras. tower. Background technique [0002] The three-axis stabilized gimbal has the characteristics of small size, light weight, low cost, flexible operation and high safety, and can be widely used in film on-site shooting, monitoring, surveying and other fields. Since the three-axis stabilized pan / tilt adopts the technical characteristics of the combination of feedforward control and feedback compensation control, it has higher stability and control accuracy, and the electronic equipment of the pan / tilt with feedforward control has some advanced characteristics, resulting in these stable platforms. produces a relatively stable bias. Some other mechanically stabilized platforms, due to the si...

Problems solved by technology

Since the three-axis stabilized pan / tilt adopts the technical characteristics of the combination of feedforward control and feedback compensation control, it has higher stability and control accuracy, and the electronic equipment of the pan / tilt with feedforward control has some advanced characteristics, resulting in these stable platforms. produces a relatively stable bias

Some other mechanically stabilized platforms, due to the simple mechanical structure, are not very flexible, and cannot eliminate the impact caused by low-frequency shaking or body tilt, making it difficult to shoot high-quality images, and cannot meet professional needs
