Current closed-loop control and field orientation analysis of an induction motor in six-step operation for railway applications

In railway traction drive systems, six-step operation is widely used for motors in a flux-weakening region. Traditional vector control algorithms in six-step operation cannot work effectively due to the limitation of a single degree of freedom. This study analyses the dq current coupling relationshi...
