Three-Phase PMLSM Drive

This example shows how to control the position in a three-phase permanent magnet linear synchronous machine (PMLSM) drive. The Control subsystem uses a PI-based cascade control structure with an outer position control loop, a speed control loop, and two inner current control loops. A controlled three-phase converter feeds the PMLSM. The simulation uses step references. The Scopes subsystem contains scopes that allow you to see the simulation results.
