What is the Purpose of a PID Controller’s Integral Term? Why is PI Control So Widely Used in Industry?
In the realm of process control it makes complete sense that the primary goal is – you guessed it – to control the process. For decades the PID controller has proven a reliable tool for fulfilling that objective. Even so, there are various forms of the controller that can be used and each has its unique performance attributes. In spite of the added complexity associated with the Integral Term the PI controller is the form most widely used in industry.

Read MoreWho Benefits from Process Control Training?
No surprise, as the demographics of industrial automation continue to shift a graying workforce is giving way to a younger, greener one. More and more staff are retiring just as the “automation oracles” predicted. In tandem with that trend investments in training and skills development are recovering from previously reduced, recessionary levels. With those budgets being restored some somewhat surprising questions keep popping up: How should process manufacturers apply their newly reinstated funds? Who should attend?
Read MoreWhat is Feed-Forward Control?
In a previous post cascade control was introduced as an effective means of limiting the lag between an upset and the associated PID control loop’s correction. As practitioners know: The longer the delay in responding, the larger the negative impact on a process. Like cascade, Feed-Forward enables the process to preemptively adjust for and counteract the effects of upstream disturbances.
Read MoreWhat is Proportional-Only Control? When Should P-Only Control be Used?
Place in Industrial Process Control.
As with most everything in process manufacturing, PID controllers require practitioners to make choices. One of those choices is which form of the controller to apply on a given regulatory control application. In a previous post the pros and cons of Derivative and the full PID were covered, and now the advantages and disadvantages of Proportional-Only control are explored. Due to performance characteristics the selection of a P-Only controller can be relatively straightforward and among a practitioner’s easier choices.
