Model-based condition monitoring of guiding rails in electro-mechanical systems

This paper presents a model-based approach for the condition monitoring of guiding rails in vertical transportation systems. A physics-based model of the system is used to estimate friction forces by means of an augmented Extended Kalman Filter (EKF). This estimation is compared to the friction forces predicted by a more detailed model of the system. This comparison, provides quantitative knowledge of the condition of the system. The difference...
