In this fifth edition we again present a text in support of a first course in control and have retained the best features of our earlier editions. For this edition, we have substantially rewritten Chapter 4 on the basic properties of feedback, placing the material in a more logical order and presenting it n a much more effective manner. We have also included a new Chapter 9 on nonlinear systems. In this chapter we have collected the bits and pieces of nonlinear problems into one place, organized them into a coherent story, and added new material in order to give a careful first introduction to this most important area. With this organization, the distractions caused by having the optional material on nonlinear systems scattered throughout the book are removed. Those instructors who wish to introduce the material earlier can easily do so, of course.
