Data Fusion Method Based On Adaptive Kalman Filtering, Bernadus Herdi Sirenden
Data Fusion Method Based On Adaptive Kalman Filtering, Bernadus Herdi Sirenden
Makara Journal of Technology
This paper discusses data fusion methods to combine the data from a rotary encoder and ultrasonic sensor. Both sensors are used in a micro-flow calibration system developed by the Research Center of Metrology LIPI. The methods studied are hierarchical data fusion and Kalman filtering. Three types of Kalman filters (KFs) are compared: the conventional Kalman filter and two adaptive Kalman filters. Moreover, a method to combine the uncertainty results from KF in hierarchical data fusion is proposed. The aim of this study is to find appropriate methods of data fusion that can be implemented in micro-flow calibration systems. Data from …
