Question

There are two basic forms of control system: open-loop and closed-loop. With closed loop there is a feedback, a system containing a comparison element, a control element, correction element, process element and the feedback involving a measurement system. Figure below shows the layout of these elements in a generic closed loop system.

Can you identify the following elements that might be present in a closed loop control system involving a thermostatically controlled furnace? In such a system, what would each element of closed-loop control below would correspond to, and why?

Control Unit, Correction Unit, Process, Controlled Variable, Measuring Device, Measured Value
