Feedback Control Systems Demystified is available as a Kindle ebook and an Apple iBook. Which is best and why did you choose to create this interactive engineering ebook in both formats?
Glad you asked!
Let me begin by explaining why I wanted to write an interactive ebook and not a print book on Feedback Control Systems. I know from personal experience that control system theory is a difficult subject to learn. It is often taught at the college level in the senior year or later in graduate school. Most textbooks on this subject are difficult to understand unless the reader has a firm grip on higher mathematics subjects, including, at a minimum, differential equations and complex variable theory. I might also mention that these textbooks typically cost well over a hundred dollars. Difficult math and high cost of textbooks are barriers to learning a subject that I believe can be taught to technicians, all types of engineering students, and any practicing engineer who never had a course in feedback controls.
Textbooks filled with graphs and equations are not, in my opinion, the way to teach or learn control system theory. I wanted to explore new methods for teaching this subject, as it is my passion to make it easier for anyone wishing to learn difficult engineering subjects like feedback control systems.
About Apple iBooks Author
Feedback Control Systems Demystified iBook turned out to be exactly what I wanted. Text, equations, videos, enhanced root locus plotters, open loop and closed loop simulators, workbooks, quizzes and more are all embedded into the ebook and are available at the touch or swipe of a finger. I wanted to get the book out to everyone who wanted to learn about feedback control systems, but there was a problem. iBooks originally could only be viewed on an Apple iPad. Shortly after I released the book, Apple made an iBooks reader available for Apple desktops and laptops that use the latest Apple operating system. I have hopes that Apple will soon make the iBooks reader available for Windows-based systems, much like they do now with QuickTime and iTunes. Unfortunately, Apple has not at this writing made the iBooks reader available for Windows computers or Google-based tablets. Amazon, on the other hand, has made the Kindle ebook reader available for just about every computer operating system. As a result, Amazon Kindle ebooks far outsell Apple iBooks. From an author's point of view this is unacceptable.
About Kindle Format 8
Unlike the Apple iBooks version of Feedback Control Systems Demystified, the Kindle Format 8 version requires the reader to be connected to the internet to enjoy the full interactivity. So although you can't access all the interactive elements unless you have an online connection, you can read it on any computer/notebook/tablet that has the Kindle Reader installed. Here are links for a few examples taken from the Kindle version of Feedback Control Systems Demystified.
