PrefaceThis text is an introduction to Simulink ®, a companion application to MATLAB ®. It is writtenfor students at the undergraduate and graduate programs, as well as for the working professional.Although some previous knowledge of MATLAB would be helpful, it is not absolutely necessary;Appendix A of this text is an introduction to MATLAB to enable the reader to begin learningboth MATLAB and Simulink simultaneously, and to perform graphical computations andprogramming.Chapters 2 through 18 describe the blocks of all Simulink libraries. Their application is illustratedwith practical examples through Simulink models, some of which are supplemented withMATLAB functions, commands, and statements. Some background information is provided forlesser known definitions and topics. Chapters 1 and 19 contain several Simulink models toillustrate various applied math and engineering applications. Appendix B is an introduction todifference equations as they apply to discrete-time systems, and Appendix C introduces the readerto random generation procedures.This text supplements our Numerical Analysis with MATLAB and Spreadsheet Applications, ISBN0−9709511−1−6. It is self-contained; the blocks of each library are described in an orderly fashionthat is consistent with Simulink’s documentation. This arrangement provides insight into how amodel is used and how its parts interact with each another.Like MATLAB, Simulink can be used with both linear and nonlinear systems, which can bemodeled in continuous time, sample time, or a hybrid of these. Examples are provided in this text.Most of the examples presented in this book can be implemented with the Student Versions ofMATLAB and Simulink. A few may require the full versions of these outstanding packages, andthese examples may be skipped. Some add−ons, known as Toolboxes and Blocksets can beobtained from The MathWorks,™ Inc., 3 Apple Hill Drive, Natick, MA, 01760-2098, USA,www.mathworks.com.To get the most out of this outstanding application, it is highly recommended that this text is usedin conjunction with the MATLAB and Simulink User’s Guides. Other references are provided inthe reference section of this text.The author wishes to express his gratitude to the staff of The MathWorks™, the developers ofMATLAB® and Simulink®, especially to Ms. Courtney Esposito, for the encouragement andunlimited support they have provided me with during the production of this text.This is the first edition of this title, and although every effort was made to correct possibletypographical errors and erroneous references to figures and tables, some may have beenoverlooked. Accordingly, the author will appreciate it very much if any such errors are brought tohis attention so that corrections can be made for the next edition.Orchard Publicationswww.orchardpublications.cominfo@orchardpublications.comTable of Contents1 Introduction to Simulink 1−1 1.1 Simulink and its Relation to MATLAB ....................................................................1−1 1.2 Simulink Demos ......................................................................................................1−20 1.3 Summary ..................................................... ...
