Common Industrial Applications of P-Only Control
Effective Disturbance Rejection “When your only tool is a hammer, every problem looks like a nail” – a concept attributed to Abraham Maslow. Such can be the situation with process control
What Is a Set Point Filter?
Names – like looks – can be deceiving. While jumbo shrimp are big relative to other shrimp there’s very little about them that could be considered gargantuan. So there should
How Can I Correct for Noise Using External Filters?
Choices, choices. In the realm of process control practitioners are regularly forced to choose between competing options. Consider a PID control loop: Should it be tuned for faster disturbance rejection
How Can I Correct for Noise Using Internal Filters?
Noise is inevitable. To one degree or another it’s evident in the data of most every production process. Sure it can be absent in academic settings and similar lab environments
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
Where Can I Purchase RSTune?
Nowhere...Because RSTune and RSLoop Optimizer Were Discontinued in 2011! Product names often outlive the products themselves. Investments made to establish a product and a brand can have a lasting impact.
Who 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
What is On-Off Control?
On-Off Control is not a highly sophisticated control method. Even so, examples of its practical, everyday use can be found all around. Look no further than the appliances in your
What 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
What 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
