无感FOC,电机正转和反转启动效果不一样

Other Parts Discussed in Thread: TMS320F28062F

TMS320F28062F做无感FOC,电机正转和反转启动效果不一样,正向启动平滑,反向启动在0速时震荡一下才启动,看到有人说要更改ForceAngle的值,但是看了手册,没找到怎么更改,请问有人知道是怎么回事吗?

  • user.h 中的这里?
    #define USER_ZEROSPEEDLIMIT (1.0 / USER_IQ_FULL_SCALE_FREQ_Hz) // 0.002 pu, 1-5 Hz typical; Hz = USER_ZEROSPEEDLIMIT * USER_IQ_FULL_SCALE_FREQ_Hz

    //! \brief Defines the force angle frequency, Hz
    //! \brief Frequency of stator vector rotation used by the ForceAngle object
    //! \brief Can be positive or negative
    #define USER_FORCE_ANGLE_FREQ_Hz (USER_ZEROSPEEDLIMIT * USER_IQ_FULL_SCALE_FREQ_Hz)
