Direct Torque Control Methods of EMU during All Speed Range

Abstract:

This paper theoretically analyzes the principle of the direct torque control method, then builds the direct torque control scheme of electric multiple-units(EMU) running during all speed range: indirect torque control in low velocity zone, eighteen polygon flux control method in moderate velocity zone and weakening hexagonal flux control strategy in high velocity zone. Simulation results show that the EMU direct torque control strategy in all speed range is feasible, and the system has good dynamic and static performance. All of the researches are available in the EMU controller research.
