Indirect Stator Flux Linkage Calculation Methods of Induction Motor

Xie Hongming, Chen Boshi  
Field control is the base of high-performance control strategy of AC motor(vector control,direct torque control,etc). For decrease the dependence of motor's parameters,especially rotor parameters,to increase control system's robustness,attention has been put in flux control using stator flux more and more recently. The key of field control is how to truly calculate the flux linkage. This paper widely analyses some popular used sta- tor flux linkage calculation methods of induction motor,discusses their essence and their advantage or disadvan- tage. Furthermore,this paper gives quantitative analysis of calculation errors caused by variable parameters and it's convergence using simulation.
