I am curious on how to determine the suitable Proportional-Derivative gain for my control system. I am referring to a quite complicated system for attitude control which not the simple closed loop transfer function with step input. How can I related the idea for tuning the gain for a simple system to my complicated attitude control system.

Well, this is a vague question...
To tune the gain you either need a model of your system and do some calculations, or if you do not have any model you can tune it experimentally.
You can start by reading this:

What is your model ? Transfer function ? State space ? Linear or not ? With delay ?

My system more or less look like this. It involve an actuator to control the plant. They are in transfer function and they are assumed to be linear.

Then you can take a look at the examples listed above and adapt them to your case.
