This Closed Loop System video is a precursor intro before moving on to What is PID video 1 and 2 (PLC PID). Then ultimately on to the PID Blueprint Course with simulator at https://bin95.com/Training_Software/PID_tuning_calculator_tips.htm

In this video you learn about feedback control and the control loop basics. If you do not know what is control system, this video will help there too. It is using a heat exchanger for closed loop system examples. Inadvertently you will also learn what is a heat exchanger and how the heat exchanger calculations are done.
