Electromechanical multi-machine system for railway modeling, analysis and control

Abstract EN

The authors develop an electrochemical multi-machine system for railway traction application.

The train bogie system constituted of two induction motors (IM), fed by one voltage source inverter (VSI) is studied.

It is piloted by a Mean Rotor Field Oriented Control (MRFOC).

This system has a depending operation amplified by strong electric, magnetic and mechanical couplings.

This study is focused on the mechanical coupling between a common load of the both motors carried out by two mechanical transmissions and two rail-wheel contacts.

So, this bogie system is a high order non-linear one.

Different simulations are presented and discussed in balanced and unbalanced system operation conditions.
