Book An Investigation of a Sampled data Self adaptive Flight Control System

Download or read book An Investigation of a Sampled data Self adaptive Flight Control System written by Daniel Hehir McGrath and published by . 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).

Book OFF LINE ADAPTIVE FLIGHT CONTROL SYSTEM

Download or read book OFF LINE ADAPTIVE FLIGHT CONTROL SYSTEM written by John Bernadyn and published by . This book was released on 1966 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A single axis Off-Line adaptive sampled data flight control system was built. It was installed flight-tested and demonstrated feasible in an F102A aircraft. The system is an outgrowth of the sampled-data adaptive system previously flight tested. The system design differs from the previously implemented adaptive system in that the signal flow is continuous in nature with the sampler in the gain computing loop rather than the forward loop. The Off-Line Adaptive Computer (OLAC) uses control loop information normally present in a basic system (surface position and airframe rate) to modify the loop gain of the control system. The principal objective of the OLAC approach is to develop a sampled data adaptive system in which the adaptive computations are performed outside of the control loop.

Book excerpt: impossible to access. It has been widely scattered in papers, reports, and proceedings ofsymposia, with different authors employing different symbols and terms. But now thereis a book that covers all aspects of this dynamic topic in a systematic manner.Featuring consistent terminology and compatible notation, and emphasizing unifiedstrategies, Adaptive Control Systems provides a comprehensive, integrated accountof basic concepts, analytical tools, algorithms, and a wide variety of application trendsand techniques.Adaptive Control Systems deals not only with the two principal approachesmodelreference adaptive control and self-tuning regulators-but also considers otheradaptive strategies involving variable structure systems, reduced order schemes, predictivecontrol, fuzzy logic, and more. In addition, it highlights a large number of practical applicationsin a range of fields from electrical to biomedical and aerospace engineering ...and includes coverage of industrial robots.The book identifies current trends in the development of adaptive control systems ...delineates areas for further research . : . and provides an invaluable bibliography of over1,200 references to the literature.The first authoritative reference in this important area of work, Adaptive ControlSystems is an essential information source for electrical and electronics, R&D,chemical, mechanical, aerospace, biomedical, metallurgical, marine, transportation, andpower plant engineers. It is also useful as a text in professional society seminars and inhousetraining programs for personnel involved with the control of complex systems, andfor graduate students engaged in the study of adaptive control systems.

Book A Feasibility Study of Self learning Adaptive Flight Control for High Performance Aircraft

Download or read book A Feasibility Study of Self learning Adaptive Flight Control for High Performance Aircraft written by Stephen G. Hoppe and published by . 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).

Book Digital Adaptive Flight Controller Development

Download or read book Digital Adaptive Flight Controller Development written by Howard Kaufman and published by . This book was released on 1974 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: A design study of adaptive control logic suitable for implementation in modern airborne digital flight computers was conducted. Two designs are described for an example aircraft. Each of these designs uses a weighted least squares procedure to identify parameters defining the dynamics of the aircraft. The two designs differ in the way in which control law parameters are determined. One uses the solution of an optimal linear regulator problem to determine these parameters while the other uses a procedure called single stage optimization. Extensive simulation results and analysis leading to the designs are presented.

Book Learning Based Adaptive Control

Download or read book Learning Based Adaptive Control written by Mouhacine Benosman and published by Butterworth-Heinemann. This book was released on 2016-08-02 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive control has been one of the main problems studied in control theory. The subject is well understood, yet it has a very active research frontier. This book focuses on a specific subclass of adaptive control, namely, learning-based adaptive control. As systems evolve during time or are exposed to unstructured environments, it is expected that some of their characteristics may change. This book offers a new perspective about how to deal with these variations. By merging together Model-Free and Model-Based learning algorithms, the author demonstrates, using a number of mechatronic examples, how the learning process can be shortened and optimal control performance can be reached and maintained. Includes a good number of Mechatronics Examples of the techniques. Compares and blends Model-free and Model-based learning algorithms. Covers fundamental concepts, state-of-the-art research, necessary tools for modeling, and control.
