Fast non-intrusive estimation of liquid-phase interface and boundary heat flux in participating media by the Kalman filtering methods

Influence of Coal Gangue Volume Mixing Ratio on the System Contact Response When Multiple Coal Gangue Particles Impacting the Metal Plate and the Study of Coal Gangue Mixing Ratio Recognition Based on the Metal Plate Contact Response and the Multi-Information Fusion

“…Kalman filter [65][66][67][68][69] is a widely used filtering method, it can obtain the system states or real signals by processing the input and observed signals which contains the noise. From Figures 16 (a) -(f), after the metal plate is impacted by coal gangue, the displacement, velocity, acceleration and each part of energy of the metal plate all present the fluctuating curves, which conceal some characteristics of the contact responses.…”
