3.1.3 Sensorless Control of PM Synchronous Motor

In home appliance applications, if the mechanical sensor is used, the sensor causes increasing cost, size, and reliability problems. To overcome these problems, sensorless control methods are implemented. Several estimation methods to get the rotor speed and position information without mechanical position sensor. The sliding mode observer (SMO) is commonly used due to the various attractive features including reliability, desired performance, and robustness against system parameter variations.
