Integrated control strategies for railway vehicles with independently-driven wheel motors

This paper studies the development of integrated control strategies for railway vehicles with independently-driven wheel motors. First, a non-linear vehicle dynamic model and motor drive strategy are presented, which are followed by an investigation of the integrated control of stabilization, steering, and traction for the vehicle. Meanwhile a reformulated Kalman filter is developed and applied to estimate the required feedback by the control system. Finally, the effectiveness and practicality of the proposed integrated controller are examined and assessed by real-time simulation based on host-target computer technology provided by Matlab/Simulink.
