Aircraft control method, device and aircraft

Abstract

The invention provides an aircraft control method and device, and an aircraft. The method comprises: collecting an initial flight state parameter outputted by a power system of an aircraft; accordingto the initial flight state parameter and a preset reference signal, generating an initial control signal; inputting the initial control signal into the power system of the aircraft, collecting a current flight state parameter outputted by the power system, and calculating an error signal between the current flight state parameter and a reference signal; generating a compensation control signal based on the error signal; and according to the initial control signal and compensation control signal, determining throttle valve and rudder deflection angle control signals of the aircraft so as to control the flight state of the aircraft. Therefore, influences caused by various uncertain factors generated during the flight of the aircraft can be suppressed and the tracking control performance ofthe flight state of the aircraft by the controller is improved. Meanwhile, with the linear time-invariant control method, the aircraft control method and device are easy to realize and the practicality is high.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an aircraft control method, device and aircraft. Background technique [0002] High-speed aircraft are widely used in many fields because of their fast, efficient and reliable access to adjacent space. During the flight of high-speed aircraft, it will be affected by nonlinearity and uncertainties including parameter uncertainty, nonlinear coupling, unstructured and external interference, especially when performing supersonic missions, these uncertainties will be serious Affects the tracking performance of the closed-loop control system in the aircraft. However, in the existing control methods, the influence of uncertainty is often ignored, or these influences are roughly estimated, resulting in a poor ability to suppress the uncertain factors of the aircraft, which in turn leads to poor tracking control performance. Contents of the invention [0003] In view of this, the obj...
