Overview of PID Control terms
PID control can be a confusing concept to understand. Here, a brief summary of each term within PID (P. I,
Control Systems
We have the largest collection of Industrial Control Systems articles like industrial automation, Distributed Control Systems (DCS).
Derivative (Rate) Control Theory
The final element of PID control is the “D” term, which stands for derivative. This is a calculus concept like
Integral (Reset) Control Theory
Imagine a liquid-level control system for a vessel, where the position of a level-sensing float sets the position of a
Proportional-only Offset
A fundamental limitation of proportional control has to do with its response to changes in setpoint and changes in process
Proportional-only Control Theory
Imagine a liquid-level control system for a vessel, where the position of a level-sensing float directly sets the stem position
On/off Control Theory
Once while working as an instrument technician in an aluminum foundry, a mechanic asked me what it was that I
Feedback Control Principle
Before we begin our discussion on process control, we must define a few key terms. First, we have what is
What is a Active Barrier ?
An active barrier uses transformers, optoisolators or relays to provide isolation between the hazardous area and the non-hazardous area. It
Zener Diode Barrier Principle
The zener diode barrier works by diverting potentially dangerous energy to ground before it can reach the hazardous area. Zener
