There won't be any detailed technical answer for this general question. However, based on your image, we can advise only on which Simulink blocks to use in modeling the Compressor Control System. The foundation of the modeling process is the mathematics that describe the behavior of each colored block in the compressor model. If you have designed or derived the mathematics for the blocks, you can specify them according to the MATLAB/Simulink approach.
If you are new to modeling, we encourage you to take self-paced courses such as MATLAB Onramp, Simulink Onramp, and Control Design Onramp with Simulink.
