As complex systems have numerous parts interacting with each other, they are difficult to model. Mathematical models can be used to model these complex systems, and provide an understanding of how they function. By using Simscape, engineers can develop physical models, model control systems, and test performance at the system level. It is important for learners to understand complex system modeling using Simulink, and physical system modeling using Simscape.

This week will cover

• Importance of mathematical modeling

Simscape is used to develop models that represent physical systems in the Simulink environment. It also lets users assess system-level performance. When setting up a model for simulation on Simulink, there are specific configurations to be followed. It is important for learners to understand how to model and configure simulations using Simscape.

This week will cover

• How models run in Simulink

Simulink and MATLAB are closely integrated as Simulink models can be developed, solved, and interacted with by using MATLAB scripts. These script files have a series of statements with commands and functions that can be carried out at runtime. Simulink models can also access the MATLAB Base Workspace and Model Workspace to identify required parameters. It is important for learners to understand how MATLAB and Simulink are interfaced.

• Using a script file with Simulink models
• Creating a subsystem
• Variant subsystem
• Projects
• Template
