A Comprehensive Introduction to a Dynamic Field More modeling.more controls.more electrical and mechanical devices.. The second edition contains more coverage of key topics for a comprehensive introduction to dynamic systems and control. This includes modeling and analysis techniques, the fundamentals and applications of control systems, transfer functions, sensitivity and robust control, and digital control. Engineering design is also emphasized throughout the text with case studies, design examples, problems, and extensive hardware coverage. Key Features of the Second Edition* Extensive coverage on modeling is expanded to four chapters. The selection of engineering examples and the clear writing effectively relates the math methods to the real world.* Laplace transform response techniques are introduced as needed in the context of engineering applications. This approach clearly demonstrates the need for and the power of these techniques.* Case studies are integrated throughout the text to provide in-depth treatment of practical engineering applications such as motion control system design, electromechanical system design, vehicle suspension design, and aircraft response modes.* Optional sections at the end of each chapter introduce Matlab commands and applications relevant to the chapter's topics.* Digital controller design using Matlab is covered without the need for z-transform theory.

Distribution System Modeling and Analysis, Second Edition (Electric Power Engineering) Review

This book is loaded with great examples and the problems at the end of chapters are based on these examples. There are multiple errors in this book though. Small errors. Chapter two has about 4 or 5 errors in it. I am up to chapter 6 right now and I think that every chapter so far has at least 1 error in it.

First introduced in 2001, Kersting's Distribution System Modeling and Analysis is the only textbook on computational modeling for electric power distribution systems. Computer models are only as good as their input, and this intuitive work clearly explains the principles and mathematics behind these models and provides approximation methods that help students recognize when a result is not what it should be. Using the same authoritative yet accessible approach, this second edition was updated to reflect the changes and advances in the field since the first edition appeared.
Nearly every chapter of this book has been updated according to new trends and areas of interest, new technologies, and the increasing spread of distributed generation. Most notably, this edition features a new chapter on the center-tapped transformer for providing three-wire service to single-phase customers. New discussions consider the effects of mutual coupling between overhead and underground lines running parallel for long distances, expand on the discussion of induction machines to consider the rotor circuit, and examine the effects of distributed generation technologies such as windmills on feeders.
Illustrated with numerous figures, examples, and exercises, Distribution System Modeling and Analysis, Second Edition remains the definitive textbook for teaching students to understand and model all aspects of modern distribution systems.

Modeling and Analysis of Dynamic Systems Review

I had to buy this book for my last semester in electrical engineering. It is a good choice as an introduction to mathematical tools used in representation and analysis of dynamic systems, electrical or mecanical.
First, there are a few chapters about basic notions of dynamic (translational and rotational. You can pass this part quickly if you had a few mechanic classes, because it is just to show the good way to represent systems in modeling. Next, a good explanation of state variable modeling, transfert function, linear vs non linear equations, etc, is well written, with good examples, without too advanced maths. If you have learned basic notions in calculus and linear algebra, you can follow the text pretty easily.

The book presents the methodology applicable to the modeling and analysis of a variety of dynamic systems, regardless of their physical origin. It includes detailed modeling of mechanical, electrical, electro-mechanical, thermal, and fluid systems. Models are developed in the form of state-variable equations, input-output differential equations, transfer functions, and block diagrams. The Laplace-transform is used for analytical solutions. Computer solutions are based on MATLAB and Simulink.

The Art of Computer Systems Performance Analysis: Techniques for Experimental Design, Measurement, Simulation, and Modeling Review

The Art of Computer Systems Performance Analysis: Techniques for Experimental Design, Measurement, Simulation, and Modeling

This seminal book was the most complete mainstream text on the subject when it was first published in 1991. The reason it remains popular eleven years later (which is an extraordinary life for a computer book) is because it's an applied mathematics book that focuses solely on performance analysis, simulation and measurements. Technology may change at a rapid pace, but the techniques for measuring it do not.
The book is broken into six parts consisting of 36 chapters and ten appendices. Part I is an overview of performance evaluation. I liked the chapter on common mistakes and how to avoid them, and the guidelines for selecting techniques and metrics.
Measurement techniques and tools are the focus of Part II. the eight chapters in this part address the full spectrum, including workload types, characterization techniques, capacity planning and benchmarking, and data presentation. Most of the chapters are generic enough to be timeless. The chapters covering execution monitors and accounting logs are showing their age, but the concepts are still valid. I especially liked the chapters about data presentation and ratios.
Part III is a refresher in statistics and probability, and can safely be skipped if your knowledge and skills are fresh. Part IV delves into experimental design and analysis, while Part V covers simulations. The remaining six chapters of the book, Part VI, are devoted to queuing models.
Note that although the math is clearly explained you need college level skills in order to fully comprehend the techniques presented. I recommend investing in MathCAD or a similar program to make it easy to work the exercises that end each chapter.
This book is one of the handful that will be on your bookshelf for years to come. It's probably one of the most frequently referenced works in the performance analysis, resource management and capacity planning knowledge domains. Because it has well designed exercises at the end of each chapter it's also well suited as an advanced college level text. In my opinion it's essential reading for performance and capacity analysts, and provides an excellent foundation for more specialized books, such as those by Menasce and Almeida, that address topics such as e-commerce performance, web services, etc.

Highly recommended!" -Dr. Leonard Kleinrock University of California, Los Angeles "An entirely refreshing text which has just the right mixture of theory and real world practice. The book is ideal for both classroom instruction and self-study." -Dr. Raymond L. Pickholtz President, IEEE Communications Society "An extraordinarily comprehensive treatment of both theoretical and practical issues." -Dr. Jeffrey P. Buzen Internationally recognized performance analysis expert ". it is the most thorough book available to date" -Dr. Erol Gelenbe Universit? Ren? Descartes, Paris ". an extraordinary book.. A worthy addition to the bookshelf of any practicing computer or communications engineer" -Dr. Vinton G. Cer??? Chairman, ACM SIGCOMM "This is an unusual object, a textbook that one wants to sit down and peruse. The prose is clear and fluent, but more important, it is witty." -Allison Mankin The Mitre Washington Networking Center Newsletter
