Abstract

The invention discloses a control method and device for a tilt rotorcraft. The control method comprises steps of: establishing a dynamics reference model of the tilt rotorcraft; according to the reference model, designing a control system for controlling the tilt rotorcraft; according to the reference model, determining the system state of the tilt rotorcraft and a model difference between the reference model and an actual model; operating the control system according to the system state to obtain an virtual control input; correcting the virtual control input according to the model difference to obtain an actual control input; controlling the flight of the tilt rotorcraft according to the actual control input. Thus, the corrected actual control input is used for controlling the motion of the tilt rotorcraft so that the flight of the tilt rotorcraft is stable.

Description

Technical field [0001] The present invention relates to the field of aerodynamics, in particular to a control method and control device of a tilt rotor aircraft. Background technique [0002] In related technologies, fixed-wing aircraft and rotary-wing aircraft are two representatives of aircraft with different structures, and their development has attracted great attention from countries all over the world. Fixed-wing aircraft has the advantages of long range, low noise, and fast flying speed, but it is greatly affected by the take-off and landing environment and cannot hover in the air. Rotorcraft can achieve functions such as vertical take-off and landing, low-altitude and low-speed flight, and hovering in the air, but due to its own structural limitations, it has low load capacity, high noise, and short range. [0003] Later, the tiltrotor was proposed. The tiltrotor combines the vertical take-off and landing capability of a rotorcraft and the fast flying capability of a fixed...
