It is the equivalent of a Proportional Integral controller for sinusoidal signals. |
A PI controller is designed to make a certain signal follow a certain reference, and it functions optimally for DC signals.
A P+resonant controllers transforms the Integral part, to be resonant at the frequency of the sinusoid of the reference signal, by that having an infinite gain for that frequency.
There are several good technical papers on this subject, mostly related to single phase converters grid connection.

4 times p or 4p
4t - 2p
the output of P controller depends only on the present state of the input, whereas the output of I controller depends on the whole history of the input. that is the fundamental difference between the control law of two controllers.
