This book was released on 1967 with total page 258 pages. Available in PDF, EPUB and Kindle. 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).

This book was released on 1971 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis presents a design appraoch for a self-adaptive normal acceleration control system which is required for a hypothetical aerospace vehicle that operates throughout a wide range of Mach numbers and dynamic pressures. The control problem includes the realistic complications of undesirable structural modes, a nonlinear servoactuator, and the statistical nature of the aircraft stability derivatives and bending mode parameters. A systematic design procedure is developed which employs a servoactuator control loop with a variable gain, in addition to the conventional pitch-rate and normal acceleration control loops, both of which use constant loop gains. The control system is simulated on an analog computer and tested at each flight condition, where variation of the servoactuator loop gain is accomplished manually. At each individual flight condition, this gain is adjusted to the value that would have ordinarily been dictated by an Off-Line Adaptive Computer (OLAC)4 WHICH USES ELEVATOR POSITION AND PITCH-RATE MEASUREMENTS FROM THE AIRCRAFT TO IDENTIFY AND COMPUTE CHANGES IN ELEVATOR EFFECTIVENESS. Collective examination of the analog results reveals that the aircraft responses to command inputs and wind gust disturbances meet the design specifications for the majority of the flight envelope.
