Dual-redundancy autonomous flight control system for micro-miniature unmanned helicopters

Abstract

The invention discloses a dual-redundancy autonomous flight control system for micro-miniature unmanned helicopters, which comprises an airborne control system and a ground remote control and remote measuring system, wherein the airborne control system acquires the flight data of a helicopter, controls the unmanned helicopter to fly in accordance with scheduled subjects according to a flight control algorithm, and sends the flight data and algorithm results to the ground remote control and remote measuring system through an airborne data transfer radio in the airborne control system; and the ground remote control and remote measuring system receives the data sent by the airborne control system, displays the data through a ground station so as to enable ground experimenters to know the flight and control states of the helicopter, and uploads a control instruction in real time through the ground station so as to adjust and change the flight subjects and control state of the helicopter. According to the invention, the autonomous capacity of small unmanned helicopters can be improved, and the reliability of the system can be increased; and especially, when a flight control computer has failures, the safety of a test platform can be ensured to the maximum extent.

Description

technical field [0001] The invention relates to a dual-redundancy autonomous flight control system for a miniature unmanned helicopter, which is a comprehensive design for the dual-redundancy flight control system for a miniature unmanned helicopter, and belongs to the technical field of aviation flight control. Background technique [0002] Unmanned helicopters have unique flight performance and use value. In terms of military affairs, unmanned helicopters can perform tasks including reconnaissance, surveillance, attack, and communication relay; in terms of civilian use, unmanned helicopters have broad application prospects in aerial photography, atmospheric monitoring, traffic monitoring, power inspection, forest fire prevention, etc. . In addition, because the unmanned helicopter flight control system is a nonlinear, strongly coupled, multivariable, underactuated system, it is also an excellent platform for control theory research. In recent years, the micro unmanned he...

Problems solved by technology

[0009] The single-redundancy flight control system combined with PC-104 and DSP is currently the mainstream design for the flight control of small unmanned helicopters, but the hardware complexity of the flight control system increases and the design cost increases

This kind of single-redundancy flight control system is not enough to guarantee the flight safety of helicopters in the state of sudden failure, especially when the flight missions become more and more complicated and the data transmission rate of airborne equipment is getting higher and higher. The probability of problems in the processing of the control system is getting higher and higher, and the reliability of the system is difficult to guarantee

During the flight test, the flight control computer failed and there was no backup to replace it. The equipment loss at the same time as the test failed greatly increased the test cost of the micro unmanned helicopter test platform
