SimPowerSystems

Creating Your Own Library of Models

SimPowerSystems provides a variety of basic building blocks to build more complex electric blocks. Using the masking feature of Simulink, you can assemble several elementary blocks of powerlib into a subsystem, build your own parameter dialog box, create the desired block icon, and place this new block in your personal library.

The Modeling Simple Systems chapter explained how to build a nonlinear model using a Voltage Measurement block and a Controlled Current Source block. The proposed examples (a nonlinear inductance and a nonlinear resistance) were relatively simple. Using the same principle, you can develop much more complex models using several controlled current sources, or even controlled voltage sources. Refer to the tutorial Building and Customizing Nonlinear Models.
