Modeling Engineering Systems

Modeling Engineering Systems Cover Modeling Engineering Systems was first published in 1994 by LLH Technology Publishing. The book provided the foundation necessary to develop mathematical models of dynamic electrical, mechanical, fluid and thermal systems. The book was very well received as evidenced by the many 5-star reviews on Amazon.com. The book is now out of print; however, I recently revised and updated the book. I made it available on Amazon.com in Kindle ebook format.

Math models of dynamic systems take the form of time varying, ordinary differential equations. The study of differential equations is very important in understanding automatic control systems, but usually follows the study of calculus. So to make the book accessible to as many readers as possible, I included an appendix in the book which reviews calculus and explains the development of differential equations in an easy to understand, step-by-step manner. I even use spreadsheets to show readers how easy it is to solve differential equations numerically.

During my research on the revisions to the Kindle ebook version, I discovered some websites that I think can help you understand and/or review algebra, trigonometry, and calculus. Modeling Engineering Systems assumes you have a good understanding of these subjects, so if you want a review, take a look at the two math tutorial websites listed in the right column.

Math Tutorials
