Current Decoupling and Controller Design for Induction Motors Based on Neutral Delay System

In the AC power transmission system, in order to reduce the loss of switching devices, the switching frequency of the traction converter is generally low, and a large digital control delay will occur, which will aggravate the cross coupling between the excitation component and the torque component o...
