I have simulink model
and i want to plot bode plot for output sensitivity . Normally output sensitivity measure from output to additive noise. In model i have put linearization pints at output and additive noise but i am not getting how to plot bode response for this ? can anyone tell ?

Why do you need the additive noise to find the bode plot? I would first suggest using the linear analysis tool.
First you want to determine what response you are looking for. Do you want the open loop plant response? The close loop response with the controller? I don't see anywhere you can actually command your controller to do anything.
If you want the frequency response over the plant, set the input to the plant as an open loop input point and the output of the plant as an open loop output. If you want the overall system response you would determine the input to the controller and set that as the input point and you would use the output from the plant as the output point.
