Technology, by its very nature, is a laboratory-oriented activity. As such, the laboratory portion of any technology program is vitally important. These materials are intended to provide a meaningful experience with automatic controls for students of modern technology. The topics included provide exposure to basic principles of control systems, transducers, actuators, amplifiers, and controllers. The sequence of presentation chosen is by no means inflexible. It is expected that individual instructors may choose to use the materials in other than the given sequence. The particular topics chosen for inclusion in this volume were selected primarily for convenience and economy of materials. Some instructors may wish to omit some of these exercises or to supplement some of them to better meet their local needs.
