An architecture of flight control system for unmanned aerial vehicle based on ttp/c bus

Abstract

The invention belongs to the field of flight control, and achieves a configuration scheme of an unmanned aerial vehicle (UAV) three redundancy flight control system (hereinafter referred to as a flight control system) architecture based on a TTP / C (Time-Triggered Protocol) bus. The architecture takes a high-performance digital three redundancy flight control computer (FMC) as a core control module, an external bus is formed by using the TTP / C bus based on time triggering, and the demanding requirements of an unmanned aerial vehicle for the flight control system are met. The architecture is beneficial for the unmanned aerial vehicle flight control system to develop in a highly reliable, real-time and open direction, and has a broad application space.

Description

technical field [0001] The invention belongs to the field of flight control and relates to the field of flight control systems. It is suitable for various control systems related to flight control such as aviation aircraft in the atmosphere and space and near-space aircraft. Background technique [0002] The flight control system is an important component of the entire aircraft. It is used to sense the movement of the body, combine automatic or artificial expectations, solve and output control commands, control the aerodynamic rudder surface of the aircraft and other cross-linking equipment, and realize the control of the aircraft as expected. Purpose. The flight control system is the "brain" and "hands and feet" of the aircraft, and it is also the key to ensuring flight safety and achieving mission goals. [0003] With the continuous development of aerospace technology and the continuous expansion of the application area, especially the cutting-edge control area, the requ...

Problems solved by technology

[0004] From the development of UAV technology in various military powers, it can be seen that UAVs show obvious characteristics of multi-tasking, long endurance, high maneuverability, and high dynamics, and gradually begin to replace the tasks and functions of some manned aircraft. The development characteristics have put forward strict requirements on the comprehensive performance of the UAV flight control system. However, the traditional UAV flight control system, limited by its application background, often inevitably has a single function, low real-time performance, and poor structure. Complicated, poor reliability and other shortcomings, generally do not have openness and modularity
