Three-Phase Synchronous Machine Drive

This example shows how to control the rotor speed in a Synchronous Machine (SM) based electrical drive. A high-voltage battery feeds the SM through a controlled three-phase converter for the stator windings and through a controlled two-quadrant chopper for the rotor winding. Use the model to design the SM controller, selecting architecture and gains to achieve desired performance. The Scopes subsystem contains scopes that allow you to see the simulation results.
