Paper Title
An Improved Parameter Identification Method For Three Phase Induction Motor
Abstract
In order to improve the control performance of vector inverter, an improved parameter identification solution for
induction motor is proposed in this paper. Dc or AC voltage is applied to the induction motor using the SVPWM through the
inverter. Then stator resistance, stator leakage inductance, rotor resistance, rotor leakage inductance and mutual inductance
are obtained according to the signal response. The discrete Fourier transform (DFT) is used to deal with the noise and
harmonic. The impact on parameter identification caused by delays in the inverter switch tube, tube voltage drop and deadtime
is avoided by effective compensation measures. Finally, the parameter identification experiment is conducted based on
the vector inverter which using TMS320F2808 DSP as the core processor and results show that the strategy is verified.
