This book was released on 1964-01-01 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we study theoretical and practical aspects of computing methods for mathematical modelling of nonlinear systems. A number of computing techniques are considered, such as methods of operator approximation with any given accuracy; operator interpolation techniques including a non-Lagrange interpolation; methods of system representation subject to constraints associated with concepts of causality, memory and stationarity; methods of system representation with an accuracy that is the best within a given class of models; methods of covariance matrix estimation; methods for low-rank matrix approximations; hybrid methods based on a combination of iterative procedures and best operator approximation; and methods for information compression and filtering under condition that a filter model should satisfy restrictions associated with causality and different types of memory. As a result, the book represents a blend of new methods in general computational analysis, and specific, but also generic, techniques for study of systems theory ant its particular branches, such as optimal filtering and information compression. - Best operator approximation, - Non-Lagrange interpolation, - Generic Karhunen-Loeve transform - Generalised low-rank matrix approximation - Optimal data compression - Optimal nonlinear filtering

Download or read book Computational Techniques for Chemical Engineers written by C. Storey and published by Elsevier. This book was released on 2013-10-22 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational Techniques for Chemical Engineers offers a practical guide to the chemical engineer faced with a problem of computing. The computer is a servant not a master, its value depends on the instructions it is given. This book aims to help the chemical engineer in the right choice of these instructions. The text begins by outlining the principles of operation of digital and analogue computers and then discussing the difficulties which arise in formulating a problem for solution on such a machine. This is followed by separate chapters on digital computers and their programming; the use of digital computers in chemical engineering design work; optimization techniques and their application in the selection of optimum designs; the solution of sets of non-linear algebraic equations via hill-climbing; and determination of equilibrium compositions by minimization of Gibbs free energy. Subsequent chapters discuss the solution of partial or simultaneous differential equations; parameter estimation in differential equations; continuous systems; and analogue computers.

Download or read book Applied Process Control written by Michael Mulholland and published by John Wiley & Sons. This book was released on 2016-09-26 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basic working knowledge for the practicing control engineer in industry, offered here as a handy deluxe edition comprising two volumes each devoted to methods and practical problems. Focusing on the practical implementation, the methods volume provides readers with rapid access to process modelling and control, while including the theoretical background necessary. Throughout, the essential knowledge is built up from chapter to chapter, starting with laying the foundations in plant instrumentation and control. Modelling abilities are then developed by starting from simple time-loop algorithms and passing on to discrete methods, Laplace transforms, automata and fuzzy logic. In the end, readers have the means to design simple controllers on the basis of their own models, and to use more detailed models to test them. With its clarity and simplicity of presentation, and illustrated by more than 200 diagrams, the volume supports self-study and teaches readers how to apply the appropriate method for the application required, and how to handle problems in process control. Bridging theory and practice, the second volume contains over 200 practical exercises and their solutions to develop the problem-solving abilities of process engineers. The problems were developed by the author during his many years of teaching at university and are kept brief, taken from the fields of instrumentation, modeling, plant control, control strategy design and stability of control. The algorithm flows and codes, which are mostly based on MATLAB®, are given in many cases and allow for easy translation into applications. With a clarity and simplicity of presentation, the two volumes are similarly structured for easy orientation.

Available in PDF, EPUB and Kindle. Book excerpt: Control Systems Engineering (2/E) I.J. Nagarath and M. Gopal The book provides an integrated treatment of continuous-time and discrete-time linear and continuous-time nonlinear systems for two courses at undergraduate level or one course at undergraduate level and one course at postgraduate level. The stress is on the interdisciplinary nature of the subject and examples have been drawn from various engineering disciplines to illustrate the basic system concepts. A strong emphasis is laid on modelling of practical systems involving hardware; control components of a wide variety are comprehensively covered. Time and frequency domain techniques of analysis and design of control systems have been exhaustively treated and their interrelationship established. The concepts and criteria of stability are progressively built and interspersed at suitable locations culminating in the generalized criteria of Liapunov and Popov. A chapter on sampled-data control systems covering analysis, stability and design has been added in this edition. Modern approaches are introduced through a full chapter on state variables for both continuous-and discrete-time systems; it includes observer and pole placement design. A new chapter on optimal control gives both transfer function and time domain approaches. The optimal linear regulator problem is treated through dynamic programming. This book ends with a chapter on nonlinear control systems and their analysis via phase-plane and describing function techniques. Control Systems Naresh K. Sinha An introduction to Control Systems, this book provides the reader with the basic concepts of control theory as developed over the years in both the frequency domain and the time domain. The opening chapters of the book present a unified treatment of modelling of dynamic systems, the classical material on the performance of feedback systems based on the transfer function approach and the stability of linear systems. Further, various types of frequency response plots and the compansation of control systems have been presented. In particular, the trial-and-error approach to the design of lead compensators, as found in most textbooks, has been replaced by a direct method developed in the late 1970’s. Moreover, the design of pole-placement compensators using transfer functions, the counterpart of the combined observer and state feedback controller, has been included for the first time in a book appropriate for undergraduate and practising engineers. This book is an attempt to aid the student remove the drudgery out of numerical computations, along with numerous worked examples and drill problems with answers to help the student in mastering the subject.

Download or read book New Dynamic Programming Approaches to Stochastic Optimal Control Problems in Chemical Engineering microform written by Adrian Martell Thompson and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2005 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second algorithm, a policy iteration (PI) variant employing Nystrom's discretization method, allows computation of continuous stochastic ROC policies without quadrature, function approximation, interpolation, or Monte Carlo methods. Lipschitz continuity assumptions allow reformulation of the original problem into an equivalent finite state problem solvable in a Luus-Jaakola global optimization framework. This enables exponential computation reductions relative to standard PI. Simulations, involving stochastic ROC of a nonlinear reactor, exhibited a 99.9% reduction in computation with identical accuracy. Additionally, the average performance of the policy obtained was 58.2% better than the certainty equivalence policy. The first, a Monte Carlo extension of iterative dynamic programming (IDP), reduces discretization requirements by restricting the control policy to the dominant portion of the state space. A proof of strong probabilistic convergence of IDP is derived, and is shown to extend to the new stochastic IDP (SIDP) algorithm. Simulations demonstrate that SIDP can provide significant COD mitigation in DAC applications, relative to the standard SDP approach. Specifically, a 96% computation reduction, 92% storage reduction and less than 2% accuracy loss were simultaneously achieved using SIDP. Optimal control of chemical processes in the presence of stochastic model uncertainty is addressed. Contributions are made in two areas of process control interest: dual adaptive control (DAC) and robust optimal control (ROC). These are synergistic in that DAC involves sequences of stochastic ROC problems. In chemical engineering, these problems typically have continuous state and control spaces, and are subject to a curse of dimensionality (COD) within the stochastic dynamic programming (SDP) framework. The main novelty presented here is the method by which this COD is mitigated. Existing methods to mitigate the COD include state space aggregation, function approximation (FA), or exploitation of problem structure, e.g. system linearity. The first two yield problems of reduced but still large complexity. The third is problem specific and does not generalize well to non-linear, non-convex or non-Gaussian structures. Here, two new algorithms are developed that mitigate the COD without these simplifications, with only minimal restrictions imposed on problem structure.
