How to break the loop with a transferfunction?

I am designing a synchronous boost converter. The output voltage has to be 50V. I have a mathematical design of the boost converter. I am sure that the design is correct I have verified all of the results by comparing them to another LTSpice model. My problem now is that I want to plot a Bodeplot but to do so my system has to be linearized. I did remove the switches, but my problem is now with the feed back loop which generates the varying PWM signal. When I run it I get the following error:
Simulink cannot solve the algebraic loop containing
So I have implemented a delay by using a transfer function(1/(3e-6s+1)). Because of this delay my output voltage rises to 150V
