Download or read book Harmonic Limits of Dynamical and Control Systems written by Tobias Wichtrey and published by Logos Verlag Berlin GmbH. This book was released on 2011 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we will analyze an approach to describe the rotational behaviour of dynamical systems and control systems, namely the concept of rotational factor maps. The general idea is to find a complex-valued map F on the state space that maps the dynamics onto a rotation around the origin in the complex plane. We will call such a map a rotational factor map. More formally, these rotational factor maps are eigenfunctions of the Koopman operator. This concept of rotational factor maps is closely connected to harmonic limits, which are ergodic sums (for discrete-time systems) or integrals (for systems in continuous time). It turns out that the existence of rotational factor maps is equivalent to the existence of non-zero harmonic limits. So we use harmonic limits to analyse the spectral properties of dynamical systems given by the iteration of a map, by a semi-flow or by a control system.

Download or read book Theory of Stabilization for Linear Boundary Control Systems written by Takao Nambu and published by CRC Press. This book was released on 2017-03-03 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a unified algebraic approach to stabilization problems of linear boundary control systems with no assumption on finite-dimensional approximations to the original systems, such as the existence of the associated Riesz basis. A new proof of the stabilization result for linear systems of finite dimension is also presented, leading to an explicit design of the feedback scheme. The problem of output stabilization is discussed, and some interesting results are developed when the observability or the controllability conditions are not satisfied.
Download or read book Helicopter Flight Dynamics written by Gareth D. Padfield and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behaviour of helicopters is so complex that understanding the physical mechanisms at work in trim, stability and response, and thus the prediction of Flying Qualities, requires a framework of analytical and numerical modelling and simulation. Good Flying Qualities are vital for ensuring that mission performance is achievable with safety and, in the first edition of Helicopter Flight Dynamics, a comprehensive treatment of design criteria was presented. In this second edition, the author complements this with a new Chapter on Degraded Flying Qualities, drawing examples from flight in poor visibility, failure of control functions and encounters with severe atmospheric disturbances. Fully embracing the consequences of Degraded Flying Qualities during the design phase will contribute positively to safety. The accurate prediction and assessment of Flying Qualities draws on the modelling and simulation discipline on the one hand and testing methodologies on the other. Checking predictions in flight requires clearly defined ‘mission-task-elements’, derived from missions with realistic performance requirements. High fidelity simulations also form the basis for the design of stability and control augmentation systems, essential for conferring Level 1 Flying Qualities. The integrated description of flight dynamic modelling, simulation and flying qualities forms the subject of this book, which will be of interest to engineers in research laboratories and manufacturing industry, test pilots and flight test engineers, and as a reference for graduate and postgraduate students in aerospace engineering. The Author Gareth Padfield, a Fellow of the Royal Aeronautical Society, is the Bibby Professor of Aerospace Engineering at the University of Liverpool. He is an aeronautical engineer by training and has spent his career to date researching the theory and practice of flight for both fixed-wing aeroplanes and rotorcraft. During his years with the UK’s Royal Aircraft Establishment and Defence Evaluation and Research Agency, he conducted research into rotorcraft dynamics, handling qualities and flight control. His work has involved a mix of flight testing, creating and testing simulation models and developing analytic approximations to describe flight behaviour and handling qualities. Much of his research has been conducted in the context of international collaboration – with the Technical Co-operation Programme, AGARD and GARTEUR as well as more informal collaborations with industry, universities and research centres worldwide. He is very aware that many accomplishments, including this book, could not have been achieved without the global networking that aerospace research affords. During the last 8 years as an academic, the author has continued to develop his knowledge and understanding in flight dynamics, not only through research, but also through teaching the subject at undergraduate level; an experience that affords a new and deeper kind of learning that, hopefully, readers of this book will benefit from.

Download or read book Control System Components written by Desai and published by PHI Learning Pvt. Ltd.. This book was released on 2008-12 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The operation of each component is discussed and explained in detail in order to illustrate the function and action of each component in the composite system. Examples are used wherever possible to illustrate the principles discussed. Diagrammatic illustrations are used profusely throughout the book to make the descriptive text interesting and self-explanatory. Although a large number of books dealing with the theory of control engineering are available, most of them do not deal with the varied range of components used in modern control systems. This book is an attempt to fill this need. It comprehensively covers many typical components of primary interest to the control-system engineer. A number of different types of electrical, electromechanical, electronic, hydraulic and pneumatic control devices, which form integral parts of open-loop and closed-loop control systems, have been presented to enable the students to understand all the types of control systems or equipment that they may encounter in different fields of industry. This book is especially designed to cater to the need of a one-semester course in Control System Components, particularly for the undergraduate students of Instrumentation and Control Engineering. It will also be a highly useful text for the students of Electrical Engineering and Mechanical Engineering during their study of the theory of Control Engineering. This book will teach them about the components required to build practical control systems.
