To broaden the speed range of PMSM (Permanent Magnet Synchronous Motor) for the electric vehicles and to improve the stability in the high speed and small torque operating conditions of the electric vehicles, the control strategy based on flux-weakening control algorithm, using voltage feedback method, combined with SMVSC (Sliding Mode Variable Structure Control) algorithm, using the improved exponential...
In order to improve fault recovery characteristic of high-voltage direct current transmission system(HVDC), this paper proposes voltage dependent current order limiter(VDCOL), optimizing arc extinguishing angle controlling and adopting SVC reactive power compensator and so on to improve fault recovery feature after analyzing the main factors influencing fault recovery characteristic. This paper makes...
