In Simulink, model reference technology allows you to incorporate models within other models, facilitating modular design and testing. When it comes to initializing and sharing parameters or states across referenced models, ‘Simulink.Parameter’ objects can be defined in the MATLAB base workspace or a data dictionary and used to hold parameters, including initial states. These objects can then be referenced by name within your control and plant models. Also, you can use ‘Inport’ blocks in your referenced models (control and plant models) to accept initial conditions or parameters.
