How breaking a closed loop without neither Delay or Memory block?

Dear Mr/Ms,
I am experiencing a problem in my SimScape Power System modelling, when I try to control the output voltage I need to feedback the voltage output, but I got a problem doing it, because it is a Closed Loop, but if I set in between a Delay Block, or even a Memory Block, I lose the control of the variable in the my system run without any error but I can not control the voltage output.
Best wishes

Tony, what is the error you get without the delay block? Would it possible for you to attach the model or a screenshot?

So from the screenshot of the model, it looks like you're using rapid accelerator which does not support algebraic loops. You can run the model as is by switching to accelerator or normal mode.
The only way to eliminate algebraic loops is to use delay/memory block, which, I'm guessing needs to be inserted after the Vc from tag. If this is causing instability in your system, then you'll have to retune your controller because in real life there is always a delay in the feedback signal.
