| Abstract: | Considering that the prior statistics noise of a Kalman filter does not agree with its real behavior,an adaptive unscented Kalman filter algorithm based on innovation and residual sequences is proposed to on-line estimate the statistics noise property. First,the observation noise covariance matrix is real-time tracked through innovation sequence. Then the real time variation of process noise covariance is on line estimated based on the orthogonal principle between innovated sequence and residual sequence es... |
