neers how to design and tune feedback controllers for the automated operation of chemi-cal processes. A conceptual process block diagram for a chemical process is shown in Figure 1–1. Notice that the inputs are classified as either manipulated or disturbance variables and the outputs are classified as measured or unmeasured in Figure 1–1a.
