Single-Phase Asynchronous Machine Field-Oriented Control

This example shows how to control the rotor speed in a single-phase asynchronous machine (ASM) based electrical drive using field-oriented control. An ideal torque source provides the load. The Control subsystem uses a PI-based cascade control structure with an outer speed control loop and two inner current control loops. The single-phase ASM is fed by an H bridge. The Scopes subsystem contains scopes that allow you to see the simulation results.
