Analysis of electromechanical model of traction system with single inverter dual induction motor

The purpose of this paper is to analyze an electromechanical model of a bogie, which is a main unit of traction system. Electrical model consists of parallel-connected dual induction motors, fed by a single inverter. Conventional and weighted vector controls are used as motor speed control method. Mechanical model is considered train body, wheel-rail contact, gearbox, drag force etc. This model is established using Simscape library of MATLAB. The comparison of the control methods are obtained through simulations.
