Traction/Braking Control Design for High Speed Trains Based on Force Estimation-An More Implementable Approach
As adhesion coefficient of high speed train(HST)varies with wheel-rail surface condition and running speed,it is thus rather difficult to obtain its accurate value via online measurement,making it non-trivial to design and implement traction/braking control scheme for HST.In this paper,force observers are developed to estimate the adhesion force and the resistance,respectively.Traction/braking control is then designed by making use of the estimated adhesion force and resistance with consideration of actual wheel-rail adhesion condition.The proposed controller is more implementable as compared with most existing methods.The effectiveness of the proposed control scheme is verified via simulation.
