Control Systems Engineering

An up-to-date text designed for undergraduate courses in control systems engineering and principles of automatic controls. Focuses on design and implementation rather than just the mathematics of control systems. Using a balanced approach, the text presents a unified, energy-based approach to modeling; covers analysis techniques for the models presented; and offers a detailed study of digital control and the implementation of digital controllers. Includes examples and homework problems. TABLE OF CONTENTS Systems. Modeling, Analysis, and Control. Types of Models. Linearization. Modeling Dynamic Systems. Systems of Units.
