DOWNLOAD EBOOKManual flight control system design for fighter aircraft is one of the most demanding problems in automatic control. Fighter aircraft dynamics generally have highly coupled uncertain and nonlinear dynamics. Multivariable control design techniques offer a solution to this problem. Robust Multivariable Flight Control provides the background, theory and examples for full envelope manual flight control system design. It gives a versatile framework for the application of advanced multivariable control theory to aircraft control problems. Two design case studies are presented for the manual flight control of lateral/directional axes of the VISTA-F-16 test vehicle and an F-18 trust vectoring system. They demonstrate the interplay between theory and the physical features of the systems.

DOWNLOAD EBOOKThe #1 guide to understanding the "why and how" of fly-by-wire flight control systems. This book is an approachable and easily understandable must-read for aviation professionals! Why don't new aircraft designs allow the pilots a mechanical control connection? This book explains how fly-by-wire fixes the top 5 problems with mechanical controls for high performance aircraft. Rather than describe a particular aircraft’s design with confusing acronyms, readers will get a "behind the scenes" understanding for the critical concepts that apply to any modern aircraft. Because these design principles are easily described and understood, readers of this book will be armed with knowledge as they approach their flight manual procedures. Including: - Problems with mechanical flight controls - Advantages of fly-by-wire - How and why can fly-by-wire control systems fail? - Why are four computers better than one or two? - Explanations of the control laws used by business jets, fighters, and airliners - What sensors are needed, and how the system maintains control when sensors are lost - Design considerations for risk mitigation in case of component failures Buy this book to read on your next layover!

DOWNLOAD EBOOKClassical design and analysis techniques, many of which date back to the 1950's, are still predominantly used in the aerospace industry for the design and analysis of automatic flight control and aero-engine control systems. The continued success and popularity of these techniques is particularly impressive considering the radical advances in aircraft and spacecraft design and avionics technology made over this period. Clearly, an understanding of both the advantages and limitations of these methods is essential in order to properly evaluate the likely usefulness of more modern techniques for the design and analysis of aerospace control systems. One of the themes of this book is that the multivariable robust control methods it describes are logical and natural extensions of the more classical methods, and not replacements for them. It is assumed that readers of this publication are already familiar with classical flight control techniques. Emphasis is on the philosophy, advantages and limitations of the classical approach to flight control system design and analysis. Abstracted in Inspec

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.

DOWNLOAD EBOOKThis thesis investigates the application of a singular perturbation method in the design of a complete (lateral and longitudinal) multivariable, error-actuated, tracking, computer-operated digital flight controller. The aircraft model used to test the method is a hypothisized computer aided design proposed by Lockheed with augmented flight control surfaces including horizontal and vertical canards, and jet-flaps. Separate lateral and longitudinal controllers are designed for each of three flight conditions - 0.6 Mach, sea level; 0.9 Mach, 30,000 ft. altitude; and 2.3 Mach, 40,000 ft. altitude. The lateral and longitudinal controllers for each flight condition are then combined, yielding a controller for each of the three flight conditions capable of accomplishing lateral and longitudinal maneuvers. The controllers are tested by commanding seven decoupled six degree-of-freedom maneuvers and one coupled three degree-of-freedom maneuver. Figures of Merit (rise time, percent overshoot, and settling time) are presented for the decoupled maneuvers. Tests are conducted to find a single controller capable of commanding all of the decoupled maneuvers over the entire range of the three flight conditions examined.

DOWNLOAD EBOOKMultivariable Control Systems focuses on control design with continual references to the practical aspects of implementation. While the concepts of multivariable control are justified, the book emphasises the need to maintain student interest and motivation over exhaustive mathematical proof. Tools of analysis and representation are always developed as methods for achieving a final control system design and evaluation. Features: • design implementation laid out using extensive reference to MATLAB®; • combined consideration of systems (plant) and signals (mainly disturbances); • step-by-step approach from the objectives of multivariable control to the solution of complete design problems. Multivariable Control Systems is an ideal text for graduate students or for final-year undergraduates looking for more depth than provided by introductory textbooks. It will also interest the control engineer practising in industry and seeking to implement robust or multivariable control solutions to plant problems.
