Tuning PID controller for MIMO system in simulink

Below is the simulink model of plant and controller I am trying to tune, the tuning does not give desired results. P gain results in 0 value, Can someone direct me to resources for tuning PID for MIMO system or point out what could possibly have gone wrong in my system?

Hi,

Here is the resource to tune your PI controller for a MIMO system.

You can also try this example to check for some errors that are not apparently visible in your model.
