A Feasibility Study of Self-learning Adaptive Flight Control for High Performance Aircraft
Author: Stephen G. Hoppe
Publisher:
ISBN:
Category : Automatic pilot (Airplanes)
Languages : en
Pages : 258
Book Description
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 Description
Our original ignition ''point designs'' (circa 1992) for the National Ignition Facility (NIF) were made energetically conservative to provide margin for uncertainties in laser absorption, x-ray conversion efficiency and hohlraum-capsule coupling. Since that time, extensive experiments on Nova and Omega and their related analysis indicate that NIF coupling efficiency may be almost ''as good as we could hope for''. Given close agreement between experiment and theory/modeling, we can credibly explore target enhancements which couple more of NIF's energy to an ignition capsule. We find that 3-4X increases in absorbed capsule energy appear possible, providing a potentially more robust target and (almost equal to)10X increase in capsule yield.

Synthesis of β-Lactam Antibiotics
Author: Alle Bruggink
Publisher: Springer Science & Business Media
ISBN: 9401008507
Category : Science
Languages : en
Pages : 328
Book Description
Penicillins and cephalosporins have a long history in combating bacterial infections. Despite new infectious diseases and occurring resistance, beta-lactam antibiotics will for many years to come continue to play a prominent role in our therapeutic arsenal. This book covers the industrial development of the chemical and biochemical processes used to manufacture these products, as well as looking ahead to possible future processes. The interplay between synthetic organic chemistry with the understanding and application of enzymes, modeling of fermentation processes and integration through (bio-) chemical process engineering is illustrated. In-depth scientific approaches to biocatalysis and biocatalyst development including enzyme kinetics, enzyme crystal studies and semi-rational enzyme mutations are also presented. Metabolic pathway analysis and modeling of fermentation process are treated as well as molecular precision in synthetic approaches to beta-lactams, their precursors and derivatives. Process technology studies including new reactor concepts, possible short-cut routes and improved down-stream-processing methods complete a broad view on the scope and limitations of the presently developed industrial processes including an intriguing insight into future process possibilities. This book represents an excellent case study on the transformation of traditional, stoïchiometric, organic synthesis and classical fermentations into modern (bio-) catalysis and biosynthesis based on insights in metabolic pathways and enzyme actions.
