【Abstract】 A novel stator-doubly-fed doubly salient (SDFDS) motor drive for electric vehicles was developed based on DSP TMS320F2812. The structure and working principle of the SDFDS motor are introduced, and the control algorithm of the driving system is presented. The range of PI parameter of the speed loop was obtained by system identification, and then the PI parameter was specified by simulation. The control program was built by C-language, and the experiments on a 3-phase 12/8 pole 750W SDFDS motor were carried out. The results show that the developed drive system offers good steady-state and dynamic performances, hence laying a basis for the flux weakening control and on-line efficiency optimization of the SDFDS motor.更多还原
