PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...

Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

After 33 years with Monsanto and Solutia, I can’t help thinking like a user. Even as a contractor, the user view pervades my motivations and goals. I would make a lousy sales and marketing person.

In the last installment, we were halfway through the compensator design for a buck converter. As a quick recap, when designing digital compensators, the true system gain is different from the derived ...

Many motion applications require high accuracy during and at the completions of moves. Even with perfectly optimized PID (proportional, integral, derivative) values to control position, the ...

Despite the common perception of temperature control as a mature and largely unchanging area of technology, applications such as injection-molding processes increasingly require not only precise ...

The following application note describes how to use the Zurich Instruments MFLI, a 500 kHz Lock-in Amplifier, for the purpose of measuring, stabilizing, and controlling the relative distance of two ...
