    Dear all,

    This a question regarding a regulation of DC/DC converter, I am trying to use PI controller to help tracking the output error to zero.

    By comparing the open loop and the closed loop diagram, it does not seem like their will be any oscillation at any point (is the PI controller even necessary at this case), so I am not sure where to place the pole or the zero of the PI (or should I compensate the pole @59Hz in the Feedback line)?

    I really appreciate your help.
