| Abstract |
The paper deals with the application of the extended
Kalman filters for state and parameter estimation of the
induction motor in the sensorless drive system. The mathematical
models of the extended Kalman filters used for rotor flux and
speed estimation as well as for rotor time constant estimation
were presented. Some simulation results were shown in the paper.
The influence of parameters of the induction motor equivalent
circuit on the state variable estimation quality was described. The
problem of suitable choice of Kalman filter parameters, such as
elements of the covariance matrix Q, was also discussed. The
practical realization of such Kalman filters using DSP was demonstrated
and their application for sensorless control of the induction
motor was tested in the laboratory set-up. |
