Hello Abhigya,
You can deploy the entire plant software model + Raspberry Pi GPIO blocks to raspberry pi using one of the below two workflows
1) Standalone deployment workflow --> https://www.mathworks.com/help/supportpkg/raspberrypi/ug/create-and-run-an-application-on-raspberry_pi-hardware.html
2) Monitor & Tune workflow --> https://www.mathworks.com/help/supportpkg/raspberrypi/ug/remotely-monitoring-and-controlling-an-application-on-hardware.html
Alternatively, if you just want to check how your algorithm(or plant software model in your case) works with real hw data, you may want to use "Simulink Connected I/O workflow". In this approach, the model does not get deployed onto the hardware, rather Raspberry Pi Simulink blocks communicate with the hw for all I/O needs and brings that data to your host PC which is running your simulink model. This way you can see how your plant behaves with real sensor and actuator data.
For more info on Connected I/O workflow, please see the below page.
You might also find the below image processing example with connected i/o helpful.
Thanks,
Prasanth
