Abstract: A PID Controller is a proportional-integral- derivative controller. It has been relatively unchanged since its inception in 1939. In some applications, maybe only Proportional control is needed. In other applications, PI (Proportional and Integral), are best used. Still in other applications, all three modes, PID, is your best performing loop control. You may not even know it but youve been exposed to various PID Controllers throughout your life ranging from a thermostat in your home for controlling temperature to the cruise control on a vehicle. There are numerous examples in refineries, chemical processing plants, paper mills, power plants and on and on. To fully understand and truly learn PID control would take weeks of class, lab time, and field training. This paper is not intended to make you experts in tuning but rather, provide you with the fundamentals and basic understanding that you can use as a building block in preparation for when the opportunity presents itself in the field.
