Modeling, simulation and control of an Anti Rotational PMSM for electric propulsion systems

It is necessary to verify operation of all subsystems of an electric vehicle, while experimental tests impose significant cost to the manufacturers such as test platform, equipment and various power supplies. At the same time, computer aided modeling makes it possible to reduce some of these costs. This paper concentrates on controlling speed and torque of an Anti Rotational Permanent Magnet Synchronous Motor (AR-PMSM) in an electric vehicle. This motor has inner and outer rotors and so it has two independent shafts. One of these rotors is the stator in the conventional PMSM motors. This structure has many applications like wind and hydro generators, electric vehicles and marine usages. This paper introduces an AR-PMSM, its principal and structure and gives the mathematical and simulation model. The simulation results for vector control (VC), SPWM and SVM control system show the validity of resulting model and also good dynamic performance of motor.
