| Abstract |
Field-oriented control of the induction motor fed by a variable frequency, variable voltage static converter can be realized by means of controlling the stator current vector. Field-oriented control with constant rotor flux linkage in transient can make the induction motor acquire excellent dynamic performance. But to maintain rotor flux linkage in transient constant has not made the field-oriented control exhaust the possibilities to improve the transient torque and speed response. In this paper, the principle of the field-oriented control with strengthened rotor flux linkage in transient is presented. Appropriately strengthening of the rotor flux linkage in transient by means of increasing the field component of the given stator current can make the field-oriented control obtain the optimal transient response. This paper gives the theoretical analysis and the experimental results of the field-oriented control of an induction motor with strengthened rotor flux linkage in transient. |
