Tuning a PID controller is pretty straightforward, once you know how to start and what steps to follow. In this series on motion control, we have already discussed permanent magnet brushed and ...

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.

In my previous article on loop tuning, I discussed the importance of field data collection and the importance of a methodical approach to PID tuning. I introduced the concept of the bump test and how ...

Steve Sandler explains what every engineer should know about ‘non-invasive’ stability assessments. The non-invasive stability assessment is a method that uses an output impedance measurement to ...
