Abstract : Despite recent advances in efficiency, current methodologies for space structure control design still engage significant human resources for engineering development and maintenance. The work reported in this document is part of an effort to develop neural network based controllers capable of self optimization, on line adaptation and autonomous fault detection and control recovery. Focusing on vibration suppression controllers, we reviewed previous work that experimentally demonstrated the application of a new neural network architecture to feedback control and feedforward control of tonal disturbances. New developments included efficient and completely autonomous neural network feedforward control for the case of broadband disturbances.
