| Abstract |
The paper describes a new current control algorithm with integrated measuring algorithms used for sensorless control of permanent magnet (PMSM-) synchronous motor drives. The measuring information is evaluated to detect the rotor position at low speed range using the INFORM method and at high speed range using an EMF-based model. No extra test pulses are necessary for sensorless position detection. A further advantage of the current controller with ingrated INFORM/EMF measurement is that only few parameters are necessary for control. |
