Embodiment Construction

[0098] In order to clarify the technical scheme and technical purpose of the present invention, the present invention will be further introduced below in conjunction with the accompanying drawings and specific implementation methods.

[0099] The design idea of ​​the adaptive control algorithm is to use the state estimation module instead of the fixed reference model, so that it can better represent the expected dynamic performance of the oil receiver in the actual docking situation. The control parameters of the adaptive system are adaptively updated and estimated by introducing a projection operator, and the generated adaptive signal is filtered through a low-pass filter to obtain the corresponding adaptive signal increment, and then the increment is simultaneously applied and the oil receiver and the corresponding state estimation module, and then according to the error between the two and the actual state quantity of the oil receiver, adaptively update and estimate the para...

Abstract

The invention relates to an adaptive optimal butt joint trajectory tracking flying control method for an air refueling receiving machine. The method comprises a receiver model calculation module, an uncertainty interference neural network identifier module, a tracking trajectory generation module, a state estimation module, an adaptive updating law module, an adaptive control law module and an optimal control law module and further comprises a signal acquisition sensor, an arithmetic unit for calculation and a storage. A projection operator performs adaptive updating and estimation on control parameters of an adaptive system, adaptive updating and estimation are performed on parameters of an adaptive control algorithm at the next moment, and accordingly, zero generalized errors and accurate butt joint of the receiver and a refueling tapered sleeve are achieved.

Description

technical field [0001] The invention relates to the technical field of aircraft flight control, in particular to a flight control method for adaptive optimal docking trajectory tracking of an air tanker and a receiver aircraft. Background technique [0002] Aerial refueling technology can be summed up as a flight technology in which one aircraft refuels another or several aircraft in the air to increase the endurance time and flight range. Under the offensive and defensive requirements of large areas in modern air combat, aerial refueling technology can greatly increase the combat capability of participating combat aircraft, and has gradually become an important development direction for countries to increase national defense military forces such as unmanned aerial vehicles, reconnaissance aircraft, and fighter jets and modern military aircraft. one of the basic functions. At present, due to its outstanding advantages and important military value, aerial refueling technolog...
