Proportional resonant controller
What Is A Proportional Resonant Controller?Digital Control ImplementationAcademic ReferencesB-Box / B-Board ImplementationProportional resonant controllers (abbreviated PR controllers) are a particular type of transfer function that are often implemented for the closed-loop control of systems with a sinusoidal behavior. As their name indicates, they possess both a proportional and a resonant term, which can be tuned independently. When needSee more on imperix ijera [PDF]
