This example shows how to control an asynchronous machine (ASM) using the direct-torque control method with space vector modulator. A PI-based speed controller supplies the torque reference. The direct-torque controller generates the reference voltages required by the space vector modulator. A DC voltage source feeds the ASM through a controlled average-value voltage source converter.
The plot below shows the requested and measured speed for the test, as well as the phase currents in the electric drive.
