9.1. PID Operation
This page is about the virtual device function to allow users to simulate various devices with
the real I/O by using the tuning function of PID operation.
PID (Proportional-Integral-Derivative) control is the most widely used in industrial control
systems. A regulator which is controlled in accordance with Proportional, Integral and
Derivative is called PID control for short, also called PID regulator. When the user cannot
fully grasp or measure parameters of the control system, the PID regulator is the best
solution.
The PID controller is a common feedback loop component in industrial control applications.
The controller compares the collected data with a reference value and then uses this
difference to calculate a new input value whose purpose is to allow the system data to
reach or remain at the reference value.
