Download or read book Analysis of an Electrohydraulic Aircraft Control surface Servo and Comparison with Test Results written by John W. Edwards and published by . This book was released on 1972 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of an electrohydraulic aircraft control-surface system is made in which the system is modeled as a lumped, two-mass, spring-coupled system controlled by a servo valve. Both linear and nonlinear models are developed, and the effects of hinge-moment loading are included. Transfer functions of the system and approximate literal factors of the transfer functions for several cases are presented. The damping action of dynamic pressure feedback is analyzed. Comparisons of the model responses with results from tests made on a highly resonant rudder control-surface servo indicate the adequacy of the model. The effects of variations in hinge-moment loading are illustrated.

Download or read book Robust Aeroservoelastic Stability Analysis written by Rick Lind and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Advances in Industrial Control aims to report and encourage technology transfer in control engineering. The rapid development of control technology impacts all areas of the control discipline. New theory, new controllers, actuators, sensors, new industrial processes, computer methods, new applications, new philosophies, . . . . , new challenges. Much of this deVelopment work resides in industrial reports, feasibility study papers and the reports of advanced collaborative projects. The series offers an opportunity for researchers to present an extended exposition of such new work in all aspects of industrial control for wider and rapid dissemination. The high performance control systems applications in aerospace and astronautics almost have a tradition of exploiting the most advanced control theoretical developments first. The optimal control and ffitering paradigm associated with the names of Kalman, Bucy, Anderson and Moore found application in the astronautics of the 1960'S and 1970'S. At the beginning of the 1980'S, control theory moved on to robustness, singular values and mu-analysis. This new work was associated with the names of Zames, Doyle, Glover, Balas among others. The Advances in Industrial Control monograph series have published several volumes over the years which have archived the applications experience garnered from applying robust control to the aerospace sector problems. Rick Lind and Marty Brenner add to this set with their volume on robust aeroservoelastic stability. This volume reports the application of the structured singular value to aeroelastic and aeroservoelastic aerospace problems.

Download or read book Electrohydraulic Servo Systems written by D. R. Raghavendra and published by Springer Nature. This book was released on 2023-05-05 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the fundamental concepts of electrohydraulic (EH) servo systems in detail and also presents the developments about power, quadratic response, and control flexibility of EH servo systems with applications in aircraft/aerospace engineering, mobile equipment, material/structure testing, motion simulators, and strategic defense sectors. Various topics covered in this books are systems and configurations of servo systems, components, applications, design of SISO and MIMO and control options of SISO and MIMO systems. It further includes a chapter on contamination control, fault detection and diagnosis (FDD) of these systems. The detailed working procedures and advice on implementation routines presented in this book will help readers to apply the control models and systems presented so as to make their own servo systems more efficient. The book will be useful for mechanical engineers and professionals involved in the analysis and design of electrohydraulic control systems, especially in advanced hydraulic industries, the aeronautical and space, and automotive industries. It would also be a useful reference for advanced courses in EH systems.

Download or read book Advances In Aircraft Flight Control written by MB Tischler and published by Routledge. This book was released on 2018-04-24 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a single comprehensive resource that reviews many of the current aircraft flight control programmes from the perspective of experienced practitioners directly involved in the projects. Each chapter discusses a specific aircraft flight programme covering the control system design considerations, control law architecture, simulation and analysis, flight test optimization and handling qualities evaluations. The programmes described have widely exploited modern interdisciplinary tools and techniques and the discussions include extensive flight test results. Many important `lessons learned' are included from the experience gained when design methods and requirements were tested and optimized in actual flight demonstration.
