Importance of Noise‐Spectrum Measurements for Noise Control in Railway Vehicles

Control for Railway Vehicles

Automatic Slip Control for Railway Vehicles

In the railway industry, slip control has always been essential due to the low friction between the wheels and the rail. In this master’s thesis we have gathered several slip control methods and evaluated them. These evaluations were performed in Matlab-Simulink on a slip process model of a railway vehicle. The objective with these evaluations were to show advantages and disadvantages with the ...

Advanced Control Strategies for Tilting Railway Vehicles

This paper presents the findings of the first stage of a fundamental study of the tilt control problem. A tilting railway vehicle is described via appropriate modelling and a frequency domain analysis illustrates the problems associated with straightforward feedback control. A Kalman-Bucy filter is developed based on 3 inertial measurements (body lateral acceleration, roll and yaw rate) to prov...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Cost}benefit Analysis in Railway Noise Control

A method to calculate the network-wide costs of realizing di!erent noise control possibilities and their bene"ts in terms of noise reduction for lineside inhabitants has been implemented in Switzerland. These studies have shown that an optimal cost distribution consists of spending 65% of the available "nances on rolling stock improvement, 30% on noise control barriers and 5% on insulated windo...
