Abstract: The final testing study of an intelligentcontrol of the electrohydraulic servo loading system for variable-sweepaircraft wing is presented. The loading system is characterized by nonlinearity, weak damping, strong disturbance, and interconnection of rigid and elastic parts. The tasks of stabilizing the persistent oscillation in the absence of damping, rejecting disturbance and loading with high accuracy pose difficult control problems. A simple and effective intelligent controller is proposed in the paper. The intelligent controller deal with situations that involve adjusting control parameters and selecting dynamical compensators in the face of changes in the control environment. The results of real test show that the intelligent control system has excellent dynamic performance and better robustness.
