This paper develops a novel advanced angle control scheme for the stator-doubly-fed doubly salient (SDFDS) motor for electric vehicles (EVs) based on the extreme learning machine (ELM) so as to satisfy the requirement of EVs. The SDFDS motor runs with constant torque below the base speed and with constant power by field weakening over the base speed. To achieve high torque at low speed for cranking...
As a motor designed for electric vehicles (EVs), the stator-doubly-fed doubly salient (SDFDS) motor has the advantage of regulating the field flux independently and effectively. To satisfy the demands of high efficiency and fast torque response in wide range of velocity for EVs, a loss model based controller (LMC) is used to realize the on-line efficiency optimization and high dynamic response of...
The stator-doubly-fed doubly salient (SDFDS) motor for electric vehicles rotates with constant torque below basic speed, whereas with constant power by weakening flux over basic speed. The EMF of SDFDS motor can be controlled for the constant power control by the flux-weakening in theory as the controllable of flux. But the nonlinear characteristics of SDFDS motor cause the EMF to be anomalous square-wave...
