Simulink models algorithms and physical systems using block diagrams. This book shows the basics of how to create a model, add blocks to it, connect blocks, and simulate the model. You also learn how to organize your model with subsystems, name parts of a model, and modify a model. You can model linear and nonlinear systems, factoring in real-world phenomena such as friction, gear slippage, and hard stops. You can design your models to be hierarchical by organizing groups of blocks into subsystems. This approach enables you to build discrete components that reflect your real-life system and simulate the interaction of those components.
