Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an adaptive neural network control method and device for an aircraft system. Background technique [0002] With the continuous development of control technology, UAV flight control technology has attracted widespread attention. Among them, the helicopter is a typical unmanned aerial vehicle, and controlling the flight stability of the helicopter is currently a hot topic. At the same time, because of the advantages of vertical take-off and landing, flexible maneuverability, small size, low take-off environment requirements, and low-altitude flight, more and more scientists are studying it. However, because the model system is complex and difficult to establish, and has the characteristics of nonlinearity, underactuation, strong coupling, static instability, etc., and it is inevitably affected by external disturbances during flight, these factors greatly increase t...
