Flight control debugging protecting device of multi-rotor-wing unmanned plane

Abstract

The invention provides a flight control debugging protecting device of a multi-rotor-wing unmanned plane. By the flight control debugging protecting device of the multi-rotor-wing unmanned plane, self-stabilization performance of a flight control system of the multi-rotor-wing unmanned plane can be debugged, and test safety is ensured. The flight control debugging protecting device of the multi-rotor-wing unmanned plane is based on a rigid body dynamics principle of flight of the multi-rotor-wing unmanned plane and comprises a triangular rack and four changeable flight control debugging modules; the movement type of the multi-rotor-wing unmanned plane is limited through a mechanical structure; three single degrees of freedom, including rolling, pitching and heading, of the flight control system of the unmanned plane can be debugged independently, and the three degrees of freedom can be debugged comprehensively; after control responses of the multi-rotor-wing unmanned plane are observed when the protecting device runs on different modules, actual performance of new skills and new methods which are used by the unmanned plane are clear; and self-stabilization of the flight control system can be subjected to functional partitioning, research and development engineering management is facilitated, debugging of the unmanned plane can be protected, possible property loss caused by blind trial flight is avoided, research and development risks and difficulties are reduced, and development of the industry of multi-rotor-wing unmanned planes is promoted.

AI Technical Summary

Problems solved by technology

However, in stark contrast, in the field of practical application, the development of new flight control algorithms is not rapid, and the transformation of scientific research results is very slow

After a large number of theoretically very advanced algorithms were proposed, they could not be put into practical application because of their immaturity and instability. Many excellent ideas were shelved after they were proposed, and could not be further tested and improved. Therefore, the work cannot be carried out

The reason is that drones are expensive and easily damaged equipment. Many advanced flight control algorithms are low in completion and poor in stability. Cause the participants of the related research to suffer greater economic loss

However, a new flight control algorithm needs to be repeatedly debugged from its proposal to its perfection. Researchers will have to take the risk of suffering heavy losses and carry out a large number of test flights before they can complete the work. The risk of research is very high.

This has objectively greatly increased the research and development cost of new flight control algorithms in the application field, and directly affected the speed at which new theories are transformed into new achievements.
