摘要

This paper presents an Interacting Multiple Model (IMM) estimator that performs a reliable train location based on soft-switching between two kinematic train models: one assuming constant velocity and the other assuming constant acceleration. Two sensors provide input to the system, namely an eddy current sensor device measuring the velocity and a Global Navigation Satellite System (GNSS) sensor unit delivering absolute position information. Simulations show that the presented location system offers robust and accurate position information, even in case of sensor failures or GNSS signal discontinuances.
