Recently, with the development of home appliances and industrial equipment, most automation equipment has been used in industry. The most common equipment used is the motor, which requires accurate and efficient control. Additionally, motor operation requires rotor angle and speed information, which is obtained using an encoder and resolver. However, the sensor has drawbacks, including high cost, increased volume, and sensitivity to the environment. Therefore, many studies have recently been conducted on sensorless controls. In this paper, the proposed full-order flux observer method is based on flux estimation.
