Robust compensation control method of high-speed aircraft and high-speed aircraft

Abstract

The invention provides a robust compensation control method of a high-speed aircraft and the high-speed aircraft, and relates to the technical field of high-speed aircraft control. The method comprises the steps of acquiring the flight parameters of a detected high-speed aircraft; inputting the flight parameters into a robust controller which comprises an optimal controller for realizing the expected tracking performance of a nominal system and a robust compensator for inhibiting the influence of equivalent disturbance on a closed-loop control system; importing the optimal controller and the robust compensator into a preset high-speed aircraft longitudinal model to obtain a target control variable, and controlling the high-speed aircraft according to the target control variable. The robustcompensation control method of the high-speed aircraft and the high-speed aircraft are provided. An optimal controller for realizing the expected tracking performance of a nominal system and a robustcompensator for inhibiting the influence of equivalent disturbance on a closed-loop control system are used for controlling the high-speed aircraft, and the tracking performance of the high-speed aircraft can be improved.

Description

technical field [0001] The invention relates to the technical field of high-speed aircraft control, in particular to a robust compensation control method for high-speed aircraft and the high-speed aircraft. Background technique [0002] High-speed aircraft are critical platforms for effectively approaching near space and enabling immediate global strike. Because the dynamics of high-speed aircraft involves multiple factors such as the complexity of the control model, parameter uncertainty, strong coupling, non-modelling, nonlinearity, and external atmospheric disturbances, the design of high-speed aircraft controllers becomes extremely complicated. [0003] In recent years, scholars at home and abroad have done a lot of research on the design of robust controllers for high-speed aircraft. Parker et al. realized the height and velocity tracking control of high-speed aircraft based on the nonlinear geometric control technology of approximate feedback linearization. Stengel et ...
