Good question.
PID is an acronym for Proportional – Integral – Derivative. A PID control loop is the industrial standard for a feedback control loop. The inputs to the control system are the Setpoint (where you want to be) and the Process Variable (where you are now). The output from the control system is the Control Variable (what it takes to get where you want to go).
