Dynamic Modeling and Vector Control of AC Induction Traction Motor in China Railway
Control of induction motor drive with high-performance characteristics has been developed by employing vector-control, direct-torque control also with the model predictive-control in this research paper. The coordinate transformation has been introduced and established with the mathematical-models of the induction motor(CRH3) in the two-phase rotating reference frame and the two-phase stationary reference frame. Along-with the discussion of vector control basic principle, the dynamic mathematical-model of the induction motor in the two-phase reference frame is presented. Also, the method of the rotor’s field orientation in the two-phase reference frame is presented. Based on some metro-traction motor parameters, a simulation has been presented. The simulation result verifies the principle, control performance, and characteristics of different control strategies, which are comparatively analyzed in detail.
