TI中文支持网CTRL_angleDelayComp这个函数是什么意思啊？我应该怎么调用这个函数？
inline _iq CTRL_angleDelayComp(CTRL_Handle handle, const _iq angle_pu)
{
CTRL_Obj *obj = (CTRL_Obj *)handle;
_iq angleDelta_pu = _IQmpy(EST_getFm_pu(obj->estHandle),_IQ(USER_IQ_FULL_SCALE_FREQ_Hz/(USER_PWM_FREQ_kHz*1000.0)));
_iq angleUncomp_pu = angle_pu;
_iq angleCompFactor = _IQ(1.0 + (float_t)USER_NUM_PWM_TICKS_PER_ISR_TICK * (float_t)USER_NUM_ISR_TICKS_PER_CTRL_TICK * ((float_t)USER_NUM_CTRL_TICKS_PER_EST_TICK – 0.5));
_iq angleDeltaComp_pu = _IQmpy(angleDelta_pu, angleCompFactor);
uint32_t angleMask = ((uint32_t)0xFFFFFFFF >> (32 – GLOBAL_Q));
_iq angleTmp_pu;
_iq angleComp_pu;
// increment the angle
angleTmp_pu = angleUncomp_pu + angleDeltaComp_pu;
// mask the angle for wrap around
// note: must account for the sign of the angle
angleComp_pu = _IQabs(angleTmp_pu) & angleMask;
// account for sign
if(angleTmp_pu < 0)
{
angleComp_pu = -angleComp_pu;
}
return(angleComp_pu);
}
