A direct torque control (DTC) system's startup modeling and simulation of Permanent Magnet Synchronous Motor (PMSM) on electric vehicle (EV)

In recent years, electric vehicle is coming into a new fast developing period. PMSM as one of the representatives of new technologies and products has been used in the area of controlling of motor's drive successfully. On account of its advanced control strategy and differences from conventional Vector Control of motor, DTC of PMSM has becoming a hotspot for resolving. This paper gives us an introduction of the DTC control theory of PMSM which has been modeling and simulating on each part of the system via Matlab/Simulink. Moreover, the outcome of the simulation proved that the improved DTC of startup on PMSM has a good dynamic performance on EV.
