Adaptacyjny filtr Kalmana dla układu napędowego z połączeniem sprężystym

The paper presents issues related to the estimation of state variables in drive with elastic coupling in case of a variable moment of inertia of the driven machine. The introduction briefly characterized problem of torsional vibrations in electric drive. In the next chapters presents model of the drive with elastic coupling and the Kalman filter. Then dealt with various cases of operation of the estimator to accurately set the parameters of the model, on the basis of proposed algorithm for tuning the filter. Theoretical considerations was supported by simulation studies.
