Novel tilt-rotor unmanned aerial vehicle attitude control system

Abstract

The invention discloses a novel tilt-rotor unmanned aerial vehicle attitude control system. The system comprises two parts of a hardware circuit and control software, wherein the hardware circuit comprises a main control chip, a gyroscope, a sensor, a remote controller, a heading attitude control mechanism and a tilt-rotor execution mechanism, the main control chip captures an instruction of the remote controller through wireless transmission, an expected attitude of the remote controlled instruction is compared with a real-time attitude monitored by the gyroscope, a compared result serves as controlled input quantity, and a corresponding control command is output after the input quantity is operated and processed by the main control chip. By means of close integration of software and hardware, an unmanned aerial vehicle can detects real-time attitudes of the vehicle and controls movement of the heading attitude control mechanism and the tilt-rotor execution mechanism according to the remote controller instruction, and the aircraft mode can be freely switched between a fixed wing aircraft and a rotorcraft. According to the novel tilt-rotor unmanned aerial vehicle attitude control system, great practical significance is achieved for development of tilt-rotor unmanned aerial vehicles, and high reference value is achieved for development of manned tilt rotorcrafts.

Description

technical field [0001] The invention relates to the field of novel unmanned aerial vehicles, in particular to a novel attitude control system for tilt-rotor unmanned aerial vehicles. Background technique [0002] In recent years, a new type of flying tool - multi-rotor aircraft has received extensive attention and rapid development in the field of science and technology. The multi-rotor aircraft can realize vertical take-off and landing, fixed-point hovering, forward and backward, rotation, side flight and other flight actions. As a flight carrier, it can carry imaging equipment, communication equipment, acquisition equipment, special equipment, etc. into the air, and can realize the operational needs that are difficult for aviation aircraft and remote-controlled aircraft to meet. Although multi-rotor aircraft are widely used in production and life and have achieved good results, factors such as too small load, low speed, and poor endurance of multi-rotor aircraft restrict ...
