Download or read book Fundamentals of Temperature Control written by William K. Roots and published by Academic Press. This book was released on 2014-06-28 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Temperature Control focuses on theoretical foundations and principles involved in temperature control. The book first offers information on thermal-process representation and response. Discussions focus on response to damped harmonic inputs, principle of superposition, bode diagrams, ramp, step, and impulse functions, harmonic response, electrical analogs, basic equations, and thermal conductivity. The text then examines common thermal elements and open-loop temperature control. The publication ponders on closed-loop temperature control and the dynamics of discontinuous temperature control. Topics include dynamics in the phase plane and time domain, dynamic analysis, closed-loop control, secondary feedback, and cooling processes. The manuscript then examines quasi-continuous and continuous temperature control, as well as quasi-continuously controlled process behavior in the time domain and quasi-continuously controlled process behavior in the phase plane. The text is a vital source of data for researchers interested in the fundamentals of temperature control.

Available in PDF, EPUB and Kindle. Book excerpt: To anyone who worked long on the functional organization of living systems, it seems obvious that the central problems arise from a multi plicity of closed loops Simultaneously active in the control of every act. Severally, they may be stable but, combined, they may crack up or break into schizogenetic oscillation. Whatever they are, linear or not, is beside the point, for in either case the same difficulty of analysis arises. Nor does it help our argument that we deal only with formal neurons or those having greater similitude to real ones. This limited Pitts and me, in 1943, to three theorems of Part III of our "Logical Calculus of Idea Immanent in Nervous Activity. " We still seek a transparent terminology in which to discern their properties. In the face of such difficulties it takes great courage to attempt a servo system analysis of the control mechanisms me diating any reflex if one would do this as a good engineer. Walt Whitman says of the "Beginners," "How dear and dreadful they are to the earth - appearing at intervals - How all times mischoose their objects of adulation and reward - And how the same price must still be paid for the same great services!" Larry Stark is a beginner. His book must not be mistaken for phys iology - and there is nothing wrong with his physiology.
Download or read book Phase Locked Loops for Wireless Communications written by Donald R. Stephens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for the graduate or advanced undergraduate engineer. The primary motivation for writing the text was to present a complete tutorial of phase-locked loops with a consistent notation. As such, it can serve as a textbook in formal classroom instruction, or as a self-study guide for the practicing engineer. A former colleague, Kevin Kreitzer, had suggested that I write a text, with an emphasis on digital phase-locked loops. As modem designers, we were continually receiving requests from other engineers asking for a definitive reference on digital phase-locked loops. There are several good papers in the literature, but there was not a good textbook for either classroom or self-paced study. From my own experience in designing low phase noise synthesizers, I also knew that third-order analog loop design was omitted from most texts. With those requirements, the material in the text seemed to flow naturally. Chapter 1 is the early history of phase-locked loops. I believe that historical knowledge can provide insight to the development and progress of a field, and phase-locked loops are no exception. As discussed in Chapter 1, consumer electronics (color television) prompted a rapid growth in phase-locked loop theory and applications, much like the wireless communications growth today. xiv Preface Although all-analog phase-locked loops are becoming rare, the continuous time nature of analog loops allows a good introduction to phase-locked loop theory.
Download or read book Between Human and Machine written by David A. Mindell and published by JHU Press. This book was released on 2003-04-30 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, we associate the relationship between feedback, control, and computing with Norbert Wiener's 1948 formulation of cybernetics. But the theoretical and practical foundations for cybernetics, control engineering, and digital computing were laid earlier, between the two world wars. In Between Human and Machine: Feedback, Control, and Computing before Cybernetics, David A. Mindell shows how the modern sciences of systems emerged from disparate engineering cultures and their convergence during World War II. Mindell examines four different arenas of control systems research in the United States between the world wars: naval fire control, the Sperry Gyroscope Company, the Bell Telephone Laboratories, and Vannevar Bush's laboratory at MIT. Each of these institutional sites had unique technical problems, organizational imperatives, and working environments, and each fostered a distinct engineering culture. Each also developed technologies to represent the world in a machine. At the beginning of World War II, President Roosevelt established the National Defense Research Committee, one division of which was devoted to control systems. Mindell shows how the NDRC brought together representatives from the four pre-war engineering cultures, and how its projects synthesized conceptions of control, communications, and computing. By the time Wiener articulated his vision, these ideas were already suffusing through engineering. They would profoundly influence the digital world. As a new way to conceptualize the history of computing, this book will be of great interest to historians of science, technology, and culture, as well as computer scientists and theorists.

Download or read book Trackability and Tracking of General Linear Systems written by Lyubomir T. Gruyitch and published by CRC Press. This book was released on 2018-10-31 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trackability and Tracking of General Linear Systems deals with five classes of the systems, three of which are new, begins with the definition of time together with a brief description of its crucial properties and with the principles of the physical uniqueness and continuity of physical variables. They are essential for the natural tracking control synthesis. The book presents further new results on the new compact, simple and elegant calculus that enabled the generalization of the transfer function matrix concept and of the state concept, the completion of the trackability and tracking concepts together with the proofs of the trackability and tracking criteria, as well as the natural tracking control synthesis for all five classes of the systems. Features • Crucially broadens the state space concept and the complex domain fundamentals of the dynamical systems to the control systems. • Addresses the knowledge and ability necessary to study and design control systems that will satisfy the fundamental control goal. • Outlines new effective mathematical means for effective complete analysis and synthesis of the control systems. • Upgrades, completes and essentially generalizes the control theory beyond the existing boundaries. • Provides information necessary to create and teach advanced inherently upgraded control courses.

This book was released on 2015-01-29 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book reports two approaches of implementation of the essential components of a Digital Phase Locked Loop based system for dealing with wireless channels showing Nakagami-m fading. It is mostly observed in mobile communication. In the first approach, the structure of a Digital phase locked loop (DPLL) based on Zero Crossing (ZC) algorithm is proposed. In a modified form, the structure of a DPLL based systems for dealing with Nakagami-m fading based on Least Square Polynomial Fitting Filter is proposed, which operates at moderate sampling frequencies. A sixth order Least Square Polynomial Fitting (LSPF) block and Roots Approximator (RA) for better phase-frequency detection has been implemented as a replacement of Phase Frequency Detector (PFD) and Loop Filter (LF) of a traditional DPLL, which has helped to attain optimum performance of DPLL. The results of simulation of the proposed DPLL with Nakagami-m fading and QPSK modulation is discussed in detail which shows that the proposed method provides better performance than existing systems of similar type.
