5.10. Summary
The objective of this chapter was to provide an introduction to feedback control. We showed how to convert an instrumentation and control diagram to a control block diagram. Block diagram manipulations were used to develop a closed-loop transfer function. Transfer function representations for standard PID controllers were developed. The Routh array was used to test for the necessary and sufficient conditions for closed-loop stability based on the characteristic equation of the closed-loop transfer function. We noted that proportional controllers exhibit offset for setpoint and disturbance changes, motivating the development of controllers with integral action. Open-loop stable processes generally require that the controller gain ...
