Closed-loop control systems are sometimes shipped from the factory with resonances and other operational difficulties that aren't supposed to be part of the package and are not well understood.

[Rolinychupetin] insists that his recent video is not a lecture but actually a “recitation” about Bode plots. That may be, but it is still worth a watch if you want to learn more about the topic. You ...

What do engineers see when they look at a real system or conceive a new design? They will look past the hardware and visualize the flow of energy, where it is stored, and where it is dissipated. They ...

A frequency response analyzer (‘FRA’) is often used to measure gain and phase plots of control loops (Bode plots), filter responses and general frequency domain transfer functions. The FRA generally ...
