how can I implement a controller in simulink?

Hi every body. I am simulating a real-time system using the simulink, in which the data from previous time is needed. Hence a Transport Delay block has been used. in addition, the system should finally be implemented on hardware (FPGA). Now, for real-time purpose, I need a controller to simulate my code for 1000 times for example. How can I use a controller and which controller is needed? a picture of my model in simulink has been attached
