This paper presents a modified hysteretic controller to improve Direct Torque Control (DTC) of the Doubly-Fed Induction Generator (DFIG) to achieve constant switching frequency and reduced torque and flux ripples. The proposed controller generates appropriate voltage vector with variable magnitude and angle, in order to reduce those ripples. The Space Vector Modulation is employed to apply the reference...
This paper describes design of a new control and PWM algorithms for a main drive of a multisystem locomotive with special focus on investigation into the trolley-wire current which could disturb railway safety systems. Designed control is based on rotor flux oriented vector control in Cartesian coordinates which is unusually operated due to specific PWM in whole speed range. We employ a synchronous...
