Proportional integral derivative (PID) control is a common method used to regulate the dynamic behavior of a system. Examples are found in many industrial devices, where it’s employed for control of temperature, pressure, flow, speed, or position, to name a few typical applications.
The theory and mathematics behind PID control have been the subject of much discussion. But how does one apply this math and theory to implement a real device? To demonstrate how that’s done, this article will explore a thorough example.
