| Abstract |
This paper presents unified sensorless direct torque control method for voltage inverter – fed AC motors using space vector modulation (DTC-SVM). The control scheme is based on closed torque and flux loops with PI controllers which outputs are interpreted as commanded stator voltage vector components in the stator flux oriented coordinates. It was shown that one control scheme can be applied for induction motor (IM) and permanent magnet synchronous motor (PMSM) drives, with only minor modifications necessary. The principle of operation control method is given and simple approach to controller design is presented and discussed. Simulation and DSP based experimental results illustrate the theoretical considerations are presented. |
