Chapter 1. Introduction
The goal of this chapter is to provide a motivation for, and an introduction to, process control and instrumentation. After studying this chapter, the reader, given a process, should be able to do the following:
Determine possible control objectives, input variables (manipulated and disturbance) and output variables (measured and unmeasured), and constraints (hard or soft), as well as classify the process as continuous, batch, or semicontinuous
Assess the importance of process control from safety, environmental, and economic points of view
Sketch a process instrumentation and control diagram
Draw a simplified control block diagram
Understand the basic idea of feedback control
Understand basic sensors (measurement devices) ...
