The plant process,transfer functions are unknown. I have the input and output data in decimal, but on the board all of the calculations are happening in fixed point.

Hi Vishwanath,
I understand that you would like to simulate a PID controller in MATLAB, and you are looking for resources to get started.
For designing a PID controller, the simplest solution would be to use the 'pid' function available in the Control System Toolbox. You can also use the PID Tuner app to interactively design and tune a PID controller. See the following links for more information:
For converting your design from floating point to fixed point, there are options for using MATLAB Coder or HDL Coder. You can use the following examples to get started:
