Pulse is Okay, but Doublet is Better
The Pulse and Doublet tests both allow practitioners to observe the process moving in opposite directions, but which is better?

The Pulse and Doublet tests both allow practitioners to observe the process moving in opposite directions, but which is better?
Professionals who tune PID controllers using manual methods tend to agree that understanding the Process Gain of their system is of the up-most importance. Among industry practitioners the Process Gain
While a typical Distributed Control System (DCS) keeps a watchful eye on production and scheduling there are other important details that a DCS simply overlooks. To be clear, a
Modeling is a time-tested approach for decoding a process’ dynamic behavior. By understanding how a process responds to change it’s possible to apply an appropriate and timely counter measure.
Tuning PID controllers is a multi-step process. While it is important to understand each step in the process, performing the bump test and collecting dynamic data is the most crucial
If you’re old enough to remember silent movies, then you know what it’s like to see the characters seemingly jiggle around the screen. Black spots would randomly appear as the
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
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
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
The manner in which a measured process variable responds over time to changes in the controller output signal is fundamental to the design and tuning of a PID controller.
