异步电机直接转矩控制与Space Vector Modulator

Open Model

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.
