sensors, or use sensors in an open-loop fashion. The general architecture of a closed-loop control system is shown in Figure 1, where the key idea is that information from the plant is sensed, and used in computing the signal to send to the actuator. In order to describe the behavior of these systems, we will require mathematical mod-
