    <dct:description>&lt;p&gt;This is a 1996 textbook.&lt;/p&gt; &lt;p&gt;With the increasing complexity of processes to be analysed, the&lt;br&gt; modern control engineer often needs to develop a model of the system&lt;br&gt; to be controlled. However, in many cases, there is limited time for&lt;br&gt; detailed system analysis, and the engineer may not be an expert in&lt;br&gt; that particular system domain. This book is aimed at graduate&lt;br&gt; engineers (and postgraduate students) who wish to use a systematic&lt;br&gt; approach to model development that is suited to computer-aided&lt;br&gt; modelling environments.&lt;/p&gt; &lt;p&gt;The goal of this book is to support the use of modelling as a&lt;br&gt; useful knowledge-enhancing exercise, and to propose&lt;br&gt; corresponding modelling methodologies. The motivation for this&lt;br&gt; is the widespread use of models in analysing and simulating&lt;br&gt; systems for safe and cost-effective evaluation of new&lt;br&gt; processes. The context is primarily that of control system&lt;br&gt; design, due to the extensive use of models of the process, and&lt;br&gt; its disturbances, in modern design methods.&lt;/p&gt; &lt;p&gt;We use the term metamodelling to describe the approach taken;&lt;br&gt; i.e. a modelling methodology which transcends the accepted&lt;br&gt; mathematical models for specific applications. This methodology&lt;br&gt; abstracts general models from first principles, by&lt;br&gt; employing an existing notation (bond graphs) as a metalanguage&lt;br&gt; for describing physical systems. This book is, therefore,&lt;br&gt; concerned with separating out the model development process&lt;br&gt; from the functions for which the model is developed, in order&lt;br&gt; to enhance understanding of the essentials of the real physical&lt;br&gt; systems.&lt;/p&gt; &lt;p&gt;This book is organised in two parts, so that the reader may&lt;br&gt; first understand the motivation and the basic concepts, and&lt;br&gt; then have the proposed methodology illustrated by a variety of&lt;br&gt; examples covering a wide selection of applications.&lt;/p&gt; &lt;p&gt;The first part describes general modelling principles, based on&lt;br&gt; system decomposition, first using classical dynamical analysis&lt;br&gt; and then via the energy bond graph notation. Bond graphs are&lt;br&gt; shown to provide a powerful core model representation from&lt;br&gt; which a variety of mathematical models may be derived. Bond&lt;br&gt; graphs provide a useful means of illustrating causality which&lt;br&gt; is shown to be a crucial aspect of system modelling.&lt;/p&gt; &lt;p&gt;The second part uses specific case studies to illustrate the&lt;br&gt; application of this methodology to systematic generation of the&lt;br&gt; most widely used mathematical models. Reference is made to a&lt;br&gt; computer-aided modelling tool (MTT), which is a research modelling&lt;br&gt; toolbox which uses bond graphs to support the modelling of&lt;br&gt; dynamic processes.&lt;/p&gt; &lt;p&gt;This textbook was originally published by Prentice-Hall in 1996.
