Chapter 8 – Feedback Control

: The problem of maintaining a desired temperature in a chamber equipped with a controlled heater/cooler is discussed in this section. Basic modeling with heat transfer and control are considered. This control problem is encountered in industrial processes (for example, in furnaces and tank reactors) and in laboratory work where it is desirable to control the temperature of a sample. Similar control systems are ubiquitous in biology, automobile cruise controls, steering of ships, and many other applications. The chapter serves as an introduction to feedback control and proportional–integral–derivative (PID) controllers.
