Question

Quizplus · Accepted Answer

The error signal represents the difference between the desired control signal and the feedback signal. This difference is used by the controller to adjust the system to achieve the desired outcome. The feedback signal is the signal that is measured or sensed from the system, and the reference signal is the desired or target signal that the controller is trying to achieve. The sawtooth signal is a specific waveform that is typically not used in control systems.
