Patent ID: 7471997

Claim:
A landing-control device for an aircraft, comprising: a detecting unit detecting at least a relative altitude from a landing surface to the aircraft; a parameter-generating unit, comprising: a neural network that takes a detection value detected by the detecting unit as its input and, based on the detection value, outputs a landing-control parameter of the aircraft, the neural network having a feedback loop wherein an output of a first node of the neural network is input to a second node different from the first node; and a controlling unit controlling the aircraft based on the landing-control parameter output from the parameter-generating unit, wherein the output of the first node is temporally delayed and then input to the second node in the feedback loop, wherein a coupling weight coefficient in the neural network is learned by using a genetic algorithm, and wherein a landing condition of the aircraft is estimated by using plural swing models reproducing different swing motions of the landing surface such that an optimum solution fitted to an evaluation condition is set to the coupling weight coefficient.
