Direct torque controlled PWM inverter fed PMSM drive for public transport

In this paper design methodology of digital PI controllers for direct torque controlled-space vector modulated (DTC-SVM) surface Permanent Magnet Synchronous Motor (PMSM) drives for electrical trams applications has been studied. The systematical approach takes into account the full model of the SPMSM and uses analyses in discrete domain. Some simulated and experimental oscillograms of 42 kW tram drive that illustrate properties of the presented design methodology are shown.
