EN This paper describes a study and experimental verification of sensorless control of Permanent Magnet Synchronous Motor. This structure bases on the extended Kalman filter theory using only the measurement of the motor current for on-line estimation of speed, rotor position and load torque reconstruction. Control structure such as Kalman filtering, in real time requires a very fast signal processor in special way, adapted to perform complex mathematical calculations. The Digital Signal Processors have become cheaper and their performance greater. Without using position and torque sensors, it has become possible to apply described control structure as a cost-effective solution.
