Zagadnienia projektowania liniowego filtru Kalmana dla zaawansowanej struktury sterowania układu dwumasowego

In the paper the issues related to the design of extended linear Kalman filter for the state variable estimation are presented. The original two-mass system state vector is extended by the load torque and its the first as well as the second derivatives. In the introduction the modern estimation method are described briefly. Next the considered model of the drive is presented. Then the applied procedure based on the global optimization technique is presented. The robustness of the designed Kalman filter to the variation of the value of the matrix Q is examined. The simulation study are confirmed by the experimental tests.
