Abstract: Presented a simple induction motor parameter identification method. This method can identify the parameters of the induction motor in a stationary state. Experiment was carried out on speed sensorless vector control system based on TMS320F2812. Parameters obtained from the identification were input to the vector control system. LabVIEW virtual oscilloscope was used to observe the operation conditions of the system. The experimental results show that this method can identify the parameters with high accuracy. This method can be applied to speed sensorless vector control system, avoiding the cockamamie process of parameter tuning. Key words: parameter identification; stationary state; vector control; speed sensorless
