How to tune a PID Controller for a plant with two integrators?

I am designing a simulation of attitude control of a satellite using Simulink. I'm using a PID controller to control the actuation and I intend to stabilize the attitude (orientation). The output of the PID is the required actuation (torque), and the plant is used to estimate the net orientation as a result of the torque.
When I try to tune the PID controller using the Autotune feature of the Simulink PID Controller Block, I get an error saying, 'PID controller could not find an initial stabilizing controller using plant "Plant" '. One possibility is that my plant has two integrators as a result of which it may not be able to linearize the plant.

Hi Aneesh Rao,
PID controller tuning is a field many people worked on already. Have a look here for references:
If you would like to receive a more specific answer, you would have to share more information about your system to control.
Kind regards,
Robert
