| Abstract |
The paper deals with the detection of the rotor angular position of permanent magnet synchronous motors without using position encoders. Two different models are used - the INFORM model for low angular velocities and an e.m.f. based algorithm for higher velocities. Based on the detected mechanical quantities a Kalman filter is constructed which estimates angular velocity, position and load torque of the machine. The algorithms are implemented on a digital signal processing system. Measurements verify the properties of the "sensorless" drive. |
