Download or read book Control of Spacecraft and Aircraft written by Arthur E. Bryson Jr. and published by Princeton University Press. This book was released on 2015-11-03 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here a leading researcher provides a comprehensive treatment of the design of automatic control logic for spacecraft and aircraft. In this book Arthur Bryson describes the linear-quadratic-regulator (LQR) method of feedback control synthesis, which coordinates multiple controls, producing graceful maneuvers comparable to those of an expert pilot. The first half of the work is about attitude control of rigid and flexible spacecraft using momentum wheels, spin, fixed thrusters, and gimbaled engines. Guidance for nearly circular orbits is discussed. The second half is about aircraft attitude and flight path control. This section discusses autopilot designs for cruise, climb-descent, coordinated turns, and automatic landing. One chapter deals with controlling helicopters near hover, and another offers an introduction to the stabilization of aeroelastic instabilities. Throughout the book there is a strong emphasis on the mathematical modeling necessary for designing a good feedback control system. The appendixes summarize analysis of linear dynamic systems, synthesis of analog and digital feedback control, simulation, and modeling of flexible vehicles.

Available in PDF, EPUB and Kindle. Book excerpt: Timely design and development of the next generation of tiltrotor aircraft (JVX) depend heavily on in-depth understanding of existing XV-15 dynamics and the availability of fully validated simulation models. Objects of the present study are: 1. Documentation and evaluation of XV-15 bare-airframe dynamics; 2. Comparison of aircraft and simulation responses; and Development of a validated transfer-function description of the XV-15 needed for future studies. A nonparametric frequency-response approach is used which does not depend on assumed model order or structure. Transfer-function representations are derived which fit the frequency responses in the bandwidth of greatest concern for piloted handling-qualities and control-system applications. Flight tests on the VX-15 aircraft and piloted-simulation for four flight conditions from hover to cruise were planned and executed. Improved test techniques and pilot-training procedures were devised. Analytical software tools allow the identification of high-resolution spectural responses and the derivation and validation of multi-input/multi-output transfer-function models. These techniques were applied in an extensive evaluation of the open-loop flight dynamics of the XV-15 aircraft and simulation mathematical models. Deficiencies in the mathematical models were exposed and documented.
