漂移

Three short geomagnetic excursions, the Go thenburg, Mono Lake and Mungo in the Brunhes Positive Polarity period, were revealed based on the studies of magnetostratigraphy, susceptibility and δ^18O of sediments in core WP 92-5 from the central temperature area of the Western Pacific Warm Pool, and the ages of them are 12.1--11.3 kaBP, 25.0--24.0 kaBP, and 31.0--28.0 kaBP respectively. Furthermore, the Younger Dryas and Heinrich cold events were also discovered in this core by the susceptibility record.

So, the study in this dissertation focuses on some key points in theuncertainty treatment of mobile robot localization as follows: Combined with the multiple proprioceptive and exteroceptive sensors ofmobile robot MORCS-1, aimed at the drift error of fiber optic gyro as theproprioceptive sensor, the neural network using genetic algorithm as optimaltool is proposed to accomplish the modeling and calibration for temperaturedrift of fiber optic gyro, which can reduce the drift error to the standard outputat constant temperature; and aimed at the noisy disturbance of ranging datafrom the exteroceptive sensor laser scanner, a dynamic adaptive filter isintroduced through the analysis of neighboring ranging data in time and spatialcorrelation to realize the real-time and dynamic filter, which can validly filter the noisy disturbance to meet the requirement of the accurately real-timeobstacle detection in mobile robot navigation.
