- Obtain the FRD of the system that captures the important dynamics from the MIMO data (might require performing a new test with a carefully designed input rather than using the available data)
- Fit a model to the captured FRD
- Design an LQR controller using the fitted model that achieves desired performance while being robust enough for the possible modelling errors observed during step 2 via the selection of Q and R matrices
- Test the controller on the system

I am working on a project that require designing a MIMO temperature controller. I have very limited control experiences. Multiple inputs and multiple output data are available.

You would need to follow roughly 4 steps to get an LQR controller:
Depending on your knowledge in the control area these steps might be trivial or might seem impossible. I would recommend asking more specific questions once you get stuck, for instance in the modelling the system from data or selecting the Q and R matrices etc.
