Accelerating Start-Up, Optimizing PID Control
Control Station has been fortunate to partner with leading, global OEMs like Yokogawa. Award-winning products like csTuner are helping process manufacturers at all stages of operation. As GranBio in Brazil recently shared, csTuner is especially valuable during start-up when highly variable process conditions are the norm and quickly establishing safe, stable operations is the objective. Our portfolio of PID tuning products are the only ones consistently proven to handle those complex dynamics – what engineers know as the ‘real-world’.

Other Questions.
Sometimes controller design feels like a choice between the lesser of not two but three evils. P-Only Control is simple and provides a fast response, but the resulting Offset hinders tight control. PI Control addresses Offset but it leaves room for improvement. And then there’s PID Control which enhances a loop’s Set Point Tracking but typically at the expense of the associated Final Control Element (FCE). If not for the ubiquitous nature of noise in industrial applications, then PID Control would be the clear choice. But since there’s no escaping noise, what’s a practitioner to do?
Common Industrial Applications of PID Control
A previous post about the Derivative Term focused on its weaknesses. As noted, the primary challenge associated with the use of Derivative and PID Control is the volatility of the controller’s response when in the presence of noise. Noise is a major stumbling block for Derivative and PID Control as production data is routinely replete with process noise and other sources of variability. The use of PID Control in such an environment can drive frenetic changes in a loop’s Controller Output (CO) and unnecessarily wear out the associated Final Control Element (FCE). In summary: Little to gain; lots to lose.

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 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 home. Kitchen appliances such as ovens and refrigerators utilize On-Off Control. Similarly the furnaces, water heaters, and air conditioners found in most basements rely on On-Off Control. Although it’s unsophisticated, On-Off Control plays a significant role in our lives.

Ever walk onto the production floor and just sense that something was different? Whether it was something you saw, heard or even felt, a certain sixth sense kicked in and triggered an alert something’s changed. With what takes place at a production facility change is an everyday occurrence. Considering the typical facility’s size, the interconnected unit operations, the network of piping and instrumentation, and the nonstop throughput, there’s no avoiding change. In fact, a key part of the job is simply staying one step ahead of it.

Control Station is evolving. Over the years our company and the way we communicate has changed. This blog is our latest initiative to improve our communication with practitioners. As with most things we thought it would be best to begin by answering some basic questions like “Who we are?” and “What we do?”
