I am new to Simulink and I am asked to compare a model of PID control with other model, however I cant find a guide on how to compute controller effort of a controller in Simulink and also to perform robust analysis of the model. Any form of help is very much appreciated.
Thanks.

It is not 100% clear what exactly you need - time history of controller response, or a transfer function of controller response?
Either way, take a look at this video to see how to put together a closed-loop system in Simulink. Once you have the model you can simulate it to get controller effort time response as well as other signals.
For robustness analysis take a look at Robust Control Toolbox. This example is a good starting point.
