In the lecture note that I have read , it said only the following
For P controller , it is simple and easiest continuous controller to tune , fast response , relatively stable and exhibits offset at steady state.
For PI controller , it eliminate the offset , total loop will be less stable and there are two parameters to tune.
How does it help?
