Book Description
This book provides new insight on the problem of closed-loop performance and oscillations in discontinuous control systems, covering the class of systems that do not necessarily have low-pass filtering properties. The author provides a practical, yet rigorous and exact approach to analysis and design of discontinuous control systems via application of a novel frequency-domain tool: the locus of a perturbed relay system. Presented are a number of practical examples applying the theory to analysis and design of discontinuous control systems from various branches of engineering, including electro-mechanical systems, process control, and electronics. Discontinuous Control Systems is intended for readers who have knowledge of linear control theory and will be of interest to graduate students, researchers, and practicing engineers involved in systems analysis and design.
Practical Design of Flight Control Systems for Launch Vehicles and Missiles

Pages : 380
Book Description
This book gives in a concise and easy to understand form the various aspects of Practical Design of Flight Control Systems for Launch Vehicles and Missiles. It covers almost every aspect of Flight Control System Design which a designer would like to know, such as mission considerations, control requirements for various segments of the flight trajectory and different types of control effectors. It further gives generalized equations of motion with a novel method of incorporating structural flexibility and propellant sloshing which does not require rederivation, and very easy and common sense approach to deriving slosh and gimballed engine dynamic equations. Subsequently it gives the control system configurations, power plant sizing, loop design for linearised system and detailed analysis and design of on-off reaction control systems. It also covers various software features which are necessary for actual implementation of the design in flight missions, robustness features to avoid malfunctioning in some circumstances, design validation aspects including end-to-end sign checks and describes some flight experiences which called for design updates. The book is unique for its strong practical flavour and is directly useful to the working engineers in the field and post graduate students in Aerospace Engineering.

Book Description
Discontinuously working elements (on-off controls) are widely used in automatic control systems. From an engineering point of view they are attractive because they are nearly always Simpler, more rugged, and cheaper to build than continuous controls. But prediction of their effects in the controlled system is sometimes so complicated that engineers have avoided discontinuous control where it would have been preferable to continuous control. Originally published in 1953. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Self-Oscillations in Dynamic Systems
Author: Luis T. AguilarPublisher: Birkhäuser
ISBN: 3319233033
Category : Science
Languages : en
Pages : 163
Book Description
This monograph presents a simple and efficient two-relay control algorithm for generation of self-excited oscillations of a desired amplitude and frequency in dynamic systems. Developed by the authors, the two-relay controller consists of two relays switched by the feedback received from a linear or nonlinear system, and represents a new approach to the self-generation of periodic motions in underactuated mechanical systems. The first part of the book explains the design procedures for two-relay control using three different methodologies – the describing-function method, Poincaré maps, and the locus-of-a perturbed-relay-system method – and concludes with stability analysis of designed periodic oscillations. Two methods to ensure the robustness of two-relay control algorithms are explored in the second part, one based on the combination of the high-order sliding mode controller and backstepping, and the other on higher-order sliding-modes-based reconstruction of uncertainties and their compensation where Lyapunov-based stability analysis of tracking error is used. Finally, the third part illustrates applications of self-oscillation generation by a two-relay control with a Furuta pendulum, wheel pendulum, 3-DOF underactuated robot, 3-DOF laboratory helicopter, and fixed-phase electronic circuits. Self-Oscillations in Dynamic Systems will appeal to engineers, researchers, and graduate students working on the tracking and self-generation of periodic motion of electromechanical systems, including non-minimum-phase systems. It will also be of interest to mathematicians working on analysis of periodic solutions.
