Netherlands [xi] PREFACE Process dynamics and control is an inter-disciplinary area Three disciplines, process, control and information engineering, are of importance, as shown in Fig 1 • Process engineering offers the knowledge about an application Understanding a process is always the basis of modeling and control A rigorous dynamic process model should be developed to increase the understanding... .515 A2: Dynamic Process Model Development .517 A3: Dynamic Process Model Analysis 521 A4: Dynamic Process Simulation 524 A5: Process Control Simulation .530 Hints 534 Index 535 FOREWORD In 1970, Brian Roffel and I started an undergraduate course on process dynamics and control, actually the first one for future chemical and material... an appropriate way and on an appropriate hardware and software platform information framework from information technology process control X application control tools from from process technology control technology Fig 1 Process dynamics and control area in three dimensions The three disciplines process, control and information technology answer questions such as: for what, why, how, and in which way... influence of the process environment, and to techniques of model simplification The latter can be helpful, among others, in reducing the number of model parameters to be estimated I wholeheartedly recommend this book, both to students and to professional engineers, and to scientists interested in modeling of processes of any kind John E Rijnsdorp Emeritus Professor of Process Dynamics and Control University... product type and quality are the independent model variables Another important application of models is in (iv) Process Optimization These models are primarily static physical models although for smaller process plants they could also be dynamic models For debottlenecking purposes, steady-state models will suffice Process Dynamics and Control: Modeling for Control and Prediction Brian Roffel and Ben Betlem... they provide more insight into the coherence as to understand the importance of certain phenomena being observed Another application of process models is in (ii) Process Design These types of model are frequently used to design and build (pilot) plants and evaluate safety issues and economical aspects Models are also used in (iii) Planning and Scheduling These models are often simple static linear... and proceed to more complicated methods only if required The last part of the book deals with process control Guidelines are given for developing control schemes for entire plants The importance of the process model in controller tuning is shown and control of two process units with multiple inputs and multiple outputs is demonstrated Control becomes increasingly important owing to increased mass and. .. www.eigenvector.com [xv] 1 Introduction to Process Modeling The form and content of dynamic process models are on the one hand determined by the application of the model, and on the other by the available knowledge The application of the model determines the external structure of the model, whereas the available knowledge determines the internal structure Dynamic process models can be used for simulation... also of interest • Business management sets the production incentives and defines the coupling between the production floor and the office • Human factors study the relation between humans and automation The contents and format of the supplied information has to meet certain standards to enable the personnel to perform their control and supervisory tasks well This may conflict with the hierarchical structure... increase the understanding about the operation fundamentals and to test the control hypothesis Experimental model verification is essential to be aware of all uncertainties and peculiarities of the process • Control engineering offers methods and techniques for (sub-)optimal operation at all hierarchical control and operational levels For all process operational problems encountered, an appropriate or .
