I have been struggling with the design of a compensator for an analog feedback loop around a GTI using LCL grid coupling.
The only way I have made it work so far is with a type I compensator with fc so low it doesn't follow the grid half sign properly (to much lag).
There is much written on the web about this but unfortunately all for DSP implementations, has anybody any experience or pointers for analogue implementations ?
Attached (I hope) is the LTspice simulation and results for the filter itself
