초록
In a switched reluctance motor drive, it is important to synchronize the stator phase excitation with the rotor position, because the position of rotor is an essential information. In the high-speed region, switching angles are fluctuated back and forth out of the preset value, which is caused by the sampling period of the microprocessor. In this paper, a low cost analog encoder to be suitable for practical applications is proposed. The validity of the proposed analog encoder with a proper logic controller is verified from the experiments.
