Book excerpt: A study of the feasibility of a self-learning adaptive system for the flight control of high performance aircraft has been performed. A flight control system was developed for the investigation of the stability augmentation of the longitudinal axis of the F101B aircraft using self-learning adaptive control. The learning adaptive controller developed employs a three-loop concept. The innermost loop comprises a linear feedback control system in which a set of control gains is adjusted by a second (adaptive) loop employing a parameter identifier and a trainable function generator (automation). The automation provides the correct values of feedback gain in response to patterns derived from the identified aircraft parameters. The third loop (the learning loop) measures control system performance, and continually retrains the automation to improve the performance. Experiments were performed with a digital simulation of the aircraft and the learning adaptive control system. Results of the experiments indicate that learning adaptive control is feasible. However, a number of significant technical problems must be overcome prior to the use of such a control system in tactical aircraft. Studies of sensitivity must be performed to assess the effect of small perturbations in the identification parameters on system performance. Extended studies of property extraction from the identified parameters is required, and means for further simplifying the control structure is of importance in a real system. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report describes studies of the feasibility of designing adaptive systems that have adaptive ability distributed among their component elements. Each element is capable of adjusting its own behavior and each accepts a small portion of the adaptive responsibility. Adaptive systems built from these elements would display the flexibility, reliability, and damage recovery capacity found in living creatures. Analytical techniques using optimal control theory and digital and analog computer simulations were used to further the study of distributed adaptation. Trainable networks of threshold logic units, which had been proposed as modules of an adaptive controller, were analyzed and simulated on a digital computer. A trainable universal Boolean function generator was found which has guaranteed rapid convergence to any desired Boolean function. An adaptive optimal autopilot for a roll-yaw coupled, high-performance aircraft was simulated on the analog computer. An evaluation of test results provided detailed information about the convergence of the adaptation process and the effect that adaptation has on system performance. The optimal adaptive controller adapted rapidly enough to prevent violent divergence of the aircraft attitude. The results suggest that these concepts are suitable for further development. Techniques developed to instrument the adaptation process would be useful for the construction of large-scale adaptive systems. (Author).
