A Parameter Identification Method of Induction Motor Based on Three Level Inverter

The effect of vector control for Induction Motor (IM) largely depends on whether the motor parameters are accurate. This paper presents a simple method based on model of three phase induction motor. In those methods, DC test, locked-rotor test, no-load test is used to get the parameters. The reconstruction of output voltage is used to instead of voltage transducer. The Dead-time compensation strategy is appLied to this system. The FFT is used to process the signals of current and voltage Experimental results are presented to prove the effectiveness of the method.
