The complex sensorless control scheme is not practical for use in the field of home appliance systems because it is not economical. Therefore, it is necessary to introduce a simplified sensorless control scheme that is composed of least calculation to estimate the rotor position. This paper presents the principle of the rotor position estimation with comparison of the estimated flux linkage and reference flux linkage. In order to verify the feasibility of the control scheme, ACSL is used for the simulation and TI DSP TMS320F240 is used for the experiment.
