The three phase squirrel-cage induction machine is the most used motor
in industry applications (around 80% of motors), due to its simplicity,
reliability, free maintenance costs. The parameters of the three-phase
induction machine varies with temperature and magnetizing flux. The control of
the electrical drives is definitively dependent by motor parameters. Therefore,
the performances of the electric drives are directly related to the motor
parameters values. The authors of the paper propose a method in order to identify
the parameters of the three phase squirrel-cage induction motor. The control
methods of the induction motors are divided in scalar and vector controls. The
best performances of the induction motor are obtained with the vector control.
The authors use the mathematical model of the three phase squirrel-cage
induction motor in the mobile rotor magnetizing flux reference frame, related
to the vector control strategy. Despite of the most used identification
methods, the proposed method uses the dynamical model of the induction motor.
The experimental data is used in order to compare the obtained parameters from
the adopted mathematical model, and the error is minimized through the proposed
identification method. In order to validate the efficiency of the proposed
identification method, the Matlab based simulation results are presented. The
advantages of the proposed method consists of the high performances, robust and
inexpensive costs.
