| Abstract: | On the basis of the stator flux oriented control theory, a new method of the stator flux oriented control with flux, rotate speed, torque closed loop based on calculating d current directly is presented in this paper. Stator flux observation adopts a mixed model of voltage and current model. The method is analyzed that how to select the transition point in theory. It is proved that the control system has many advantages such as very good stability of stator flux and fast response of torque by simulation using the Simulink of Matlab. |
