Helicopter station-keeping; comparing LQR, fuzzy logic and neural net controllers
Helicopter station-keeping; comparing LQR, fuzzy logic and neural net controllers
Station-keeping is a difficult flight control mode for helicopters since they have little forward speed and are dynamically unstable in that mode. In this paper the designs for a fuzzy-logic controller and neural-network (NN) controllers which are used to provide acceptable station-keeping performance for a single main rotor helicopter are presented. The effectiveness of the proposed designs is established from an examination of a number of results obtained from a simulation of the controlled helicopter. The required training and recall data needed for the NN were obtained from the responses of the same helicopter type being controlled in a station-keeping mode by a continuous, linear, optimal feedback control law, obtained by solving a linear quadratic regulator problem.

Abstract
Station-keeping is a difficult flight control mode for helicopters since they have little forward speed and are dynamically unstable in that mode. In this paper the designs for a fuzzy-logic controller and neural-network (NN) controllers which are used to provide acceptable station-keeping performance for a single main rotor helicopter are presented. The effectiveness of the proposed designs is established from an examination of a number of results obtained from a simulation of the controlled helicopter. The required training and recall data needed for the NN were obtained from the responses of the same helicopter type being controlled in a station-keeping mode by a continuous, linear, optimal feedback control law, obtained by solving a linear quadratic regulator problem.
