Abstract In this paper,a new method of indirect stator field-oriented control for induction motor based on the stator current correction is proposed.The dq axis stator current and the stator flux linkage are analyzed.The relationship between q axis current and demagnetization component of stator flux linkage is calculated,and the decomposition of dq axis stator current is achieved.Using the indirect field-oriented vector control,the complexity and inaccuracy of the flux linkage observation in traditional field-oriented vector control at low speed are avoided.In order to guarantee the accuracy of the flux linkage orientation,the flux linkage orientation based on the correction of stator current error is proposed in this paper.Through the analysis of flux linkage,the dq axis dvanced current and delayed current,compensates to q axis current,and changes the slip to compensate to the error of the flux linkage orientation.Finally,the asynchronous motor of Matlab simulation model and experimental platform is established.And the results show that the system has great correction effects on the steady state operation and the variation of the motor parameters to ensure accurate static and dynamic performance.

Key words： Indirect stator field-oriented demagnetization component stator current error field orientation correction
