Abstract

The invention discloses a composite wing unmanned plane automatic pilot and a control method employed by the composite wing unmanned plane automatic pilot. Through the automatic pilot and the control guidance algorithm, a multi-shaft and fixed wing coordination control problem is solved, and full-state full-autonomous course flight of a composite wing unmanned plane is realized.

Description

technical field [0001] The invention relates to the technical field of aircraft control, in particular to an autopilot of a compound-wing unmanned aerial vehicle and a control method thereof. Background technique [0002] Compound-wing UAV is a solution for vertical take-off and landing of fixed-wing UAV. It is based on conventional fixed-wing aircraft and adds a multi-axis power unit. The pulling force generated by each propeller overcomes gravity and aerodynamic resistance to fly; while at high speed, it flies in the fixed-wing mode, overcomes gravity through aerodynamic lift, and overcomes aerodynamic resistance through the pulling forward propeller to achieve flight. Compared with other methods, the compound wing vertical take-off and landing scheme does not require additional mechanisms and has a simple structure; there is no large flight attitude change, and navigation calculation is easy. Therefore, the composite wing vertical take-off and landing solution is current...
