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 three control loops, 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.

This example has been tested on a Speedgoat Performance real–time target machine with an Intel® 3.5 GHz i7 multi–core CPU. This model can run in real time with a step size of 50 microseconds.
