This book was released on 1963 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A flight control system will adapt to changing dynamic pressure if the bandwidth of the air craft and controller is maintained several times that of an optimum series model. The Bendix System studied achieves the required bandwidth by the use of a variable-gain device that remains proportional to the inverse of airframe gain. Measured and predicted error signals are sampled to provide digital information to the variable gain circuit. (Author).

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 1967 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes analytical techniques applicable to the design of on-line digital control systems and analysis of real-time hybrid simulations. Emphasis is placed on an operational mathematics approach using state variables and signal flow mapping techniques to facilitate stability analysis and accurate interpretation of results in terms of concepts familiar to Control Engineers. Digital simulation of a fourth-order pitch rate flight control system is included. A technique for analysis of nonlinear digital systems employing Lyapunov's Second Method is presented. Predictor-corrector methods for first-order and higher-order differential equations are discussed. Error analysis techniques are included with special attention given to quantization errors. A system synthesis technique employing constraint equations for determination of control system design parameter values is developed.
