Frequency domain evaluation of a traction PMSM drive with direct torque control including field weakening area
Original language description
This paper presents a method for frequency analysis of traction drives supplied from a dc trolley wire with an input LC filter. The proposed method is suitable for frequency analysis of the traction drive in whole speed range and enables to find resonantor other observed harmonics in the operating drive circuit which could cause dangerous oscillations particularly at resonant frequencies of the power circuit. The method is used for detailed frequency analysis of a direct torque controlled traction drive with a surface mounted permanent magnet synchronous motor. The analysis is performed in a wide speed range including field weakening area and the dangerous resonant frequency is found and the behaviour of the drive in dependence on the stator frequencyis observed. A solution based on demanded machine torque correction is used for the drive stability enhancement. The behaviour of the drive with this improvement is evaluated with the proposed method as well. The proper function of the f
