This paper reports on the development of a novel neural network (NN) based airspeed estimator, and focuses on system design. In particular, a novelty detector, capable of preventing the system from producing an erroneous output during conditions in which it is known that a NN model will be extrapolating, is included within the design. A simulation model of a single main rotor helicopter was used to...
A helicopters airspeed and sideslip angle is difficult to measure at speeds below 50 knots. This paper describes the application of Artificial Neural Network (ANN) techniques to the helicopter low air-speed problem. Three ANN methods were applied to the problem: a linear network, a Radial Basis Function (RBF) network, and a Multi-Layer Perceptron (MLP), trained using an implementation of the LevenbergMarquardt...
