This book was released on 1981 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document reports the development of an incremental digitally-controlled electrohydraulic actuation system (DEHA). An electronic digital controller and a prototype DEHA unit, with an electric-stepper-motor-driven rotary distributor valve, two hydraulic drive motors, and a torque-summing gearbox, were assembled. Significant reductions in the hydraulic power normally required with a conventional geared hydraulic motor system, and some degree of hydraulic power recovery were obtained. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report describes a study of flight control actuation system with an objective to determine the degree of digitalization possible between the digital flight control processor and the control surface. A typical analog actuation system is defined as a reference for comparison with five alternates, each mechanized with increasing amounts of digital equipment. The report provides a basis for determining the direction of digital actuation systems. It verifies that distributed actuation systems are now feasible and promise enhanced performance, reliability, and cost reductions.

This book was released on 1977 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes an evaluation and presents the test results of a Digital Hardware Voter/Monitor used as an input signal selector and fault detector when used in conjunction with an electro-hydraulic control system. The DHVM operated as intended by design although asynchronous operation caused the failure detection to be frequency dependent. A digital filter could be incorporated to reduce the frequency dependency of the failure detection circuitry. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Get a complete understanding of aircraft control and simulation Aircraft Control and Simulation: Dynamics, Controls Design, and Autonomous Systems, Third Edition is a comprehensive guide to aircraft control and simulation. This updated text covers flight control systems, flight dynamics, aircraft modeling, and flight simulation from both classical design and modern perspectives, as well as two new chapters on the modeling, simulation, and adaptive control of unmanned aerial vehicles. With detailed examples, including relevant MATLAB calculations and FORTRAN codes, this approachable yet detailed reference also provides access to supplementary materials, including chapter problems and an instructor's solution manual. Aircraft control, as a subject area, combines an understanding of aerodynamics with knowledge of the physical systems of an aircraft. The ability to analyze the performance of an aircraft both in the real world and in computer-simulated flight is essential to maintaining proper control and function of the aircraft. Keeping up with the skills necessary to perform this analysis is critical for you to thrive in the aircraft control field. Explore a steadily progressing list of topics, including equations of motion and aerodynamics, classical controls, and more advanced control methods Consider detailed control design examples using computer numerical tools and simulation examples Understand control design methods as they are applied to aircraft nonlinear math models Access updated content about unmanned aircraft (UAVs) Aircraft Control and Simulation: Dynamics, Controls Design, and Autonomous Systems, Third Edition is an essential reference for engineers and designers involved in the development of aircraft and aerospace systems and computer-based flight simulations, as well as upper-level undergraduate and graduate students studying mechanical and aerospace engineering.
