calculation of lateral velocity estimation and error discrimination for railway wheelset to avoid sliding

Lateral velocity has very backbone position in the railway vehicle wheelset dynamics as it usually becomes the cause of derailment by sliding due to insufficient adhesion ratio. this inappropriate balance is pretext owing to contamination and weather procures the disturbances. this perturbation makes hindrances in the proper running of wheelset on track. to analyze the noise, the kalman filter is used based upon the railway dynamic modeling to estimate the actual signals to control the noise by measurement. thus error percentage is also computed to detect the slippage by adhesion on applicable analysis of creep coefficient. since controllable estimated lateral velocity assures minimum wheel slide.
