ABSTRACT
This chapter introduces the subject of instrumentation, as related to control engineering. Various architectures of a control system are outlined and the important role that is played by sensors and actuators in them is indicated. Important issues in the practice of control system instrumentation are identified. How instrumentation, modeling, and design of a control system are interrelated is highlighted. The steps of instrumenting a control system with sensors, transducers, actuators, and associated hardware are stated. The organization of the book is summarized.
