An electronic closed-loop control system generally consists of three elements: the controller, the input for the feedback signal (an ADC), and an output actuator (a DAC). The ADC senses and feeds back ...

Fig. 5 is a simple block diagram of the desired system. An example of a closed-loop system is the use of a thermistor for temperature feedback, with results shown in Fig. 6 .
