Abstract

Accuracy of flux amplitude and phase is critical to field-oriented control (Kim et al., 2003). The estimation of rotor flux is easily affected by rotor time constant and compensation terms are difficult to realize. In this paper, a method based on stator flux oriented is proposed. The stator flux is estimated by integrating motor EMF. The phase voltage reconstruction is obtained from DC link and vector time, and there is only one parameter R_s in the estimator of flux. The simulation results show that rotor parameter has no effect on this control method, and the system has a fast dynamic response and steady characteristics.
