Problems solved by technology

But these studies were all built on small electric UAV models and cannot be used for gas-powered UAVs
The hydraulic system is very different from the electric motor in terms of response and matching. In the transition state of tilting, the hydraulic system is restricted a lot; in addition, there is a contradiction between the overshoot and steady-state performance of the traditional PID system, so it needs to be improved. systematic research

Abstract

The invention relates to an engine control system of a tilt-rotor unmanned aerial vehicle, which is suitable for a medium-sized oil-driven tilt-rotor unmanned aerial vehicle. The system comprises an information acquisition module and a control module. The information acquisition module is mainly used for acquiring various parameters of an engine and interacting information with the engine ECU system and the control module; and the control module adopts a control strategy combining sliding mode control and PID control according to various parameters of the engine obtained by the information acquisition module so as to adapt to a helicopter mode, a fixed wing mode and a transition mode between a helicopter and a fixed wing of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle flight control, in particular to a tilt rotor unmanned aerial vehicle engine control system. Background technique [0002] On the premise of ensuring the high-speed cruise of fixed wings, the tilt-rotor aircraft has the vertical take-off and landing capability of the rotor aircraft. The take-off and landing are less restricted by the site, have high flexibility, and have broad application fields in the military. The United States has continued to develop XV-15, V-22 and other series of tilting rotor aircraft. Among them, V22 has a tilting mechanism at both ends of the wing to push the rotor upward or forward, which are used for vertical take-off and landing of helicopters or hovering and Fixed-wing flight phase. The development of tilt-rotor drones is relatively late. Based on the V22 "Osprey" manned tilt-rotor aircraft, the V247 drone developed by Bell Labs in the United States has recentl...
