This book is written as a guide for the selection and installation of observers in
control systems. It will discuss practical aspects of observers such as how to tune an
observer and what conditions make a system likely to benefit from their use. Of course,
observers have practical shortcomings, many of which will be discussed here as well.
Many books on observers give little weight to practical aspects of their use. Books
on the subject often focus on mathematics to prove concepts that are rarely helpful
to the working engineer. Here the author has minimized the mathematics while
concentrating on intuitive approaches.
