Hello, i have a question
we have been working on the control suite development kit HVMotorCtrl+PfcKit_v2.1 (HVACI_Sensorless file)
For testing purposes, we need the SVGEN_MACRO function parameter values(alpha,beta) and return values (Ta,Tb,Tc)
Does anybody know these values?
Here is the code
/* =================================================================================
File name: SVGEN.H
===================================================================================*/
#ifndef __SVGEN_H__
#define __SVGEN_H__
typedef struct { _iq Ualpha; // Input: reference alpha-axis phase voltage
_iq Ubeta; // Input: reference beta-axis phase voltage
_iq Ta; // Output: reference phase-a switching function
_iq Tb; // Output: reference phase-b switching function
_iq Tc; // Output: reference phase-c switching function
_iq tmp1; // Variable: temp variable
_iq tmp2; // Variable: temp variable
_iq tmp3; // Variable: temp variable
Uint16 VecSector; // Space vector sector
} SVGEN;

#define SVGENDQ_MACRO(v) \
v.tmp1= v.Ubeta; \
v.tmp2= _IQdiv2(v.Ubeta) + (_IQmpy(_IQ(0.866),v.Ualpha)); \
v.tmp3= v.tmp2 - v.tmp1; \
\
v.VecSector=3; \
v.VecSector=(v.tmp2> 0)?( v.VecSector-1):v.VecSector; \
v.VecSector=(v.tmp3> 0)?( v.VecSector-1):v.VecSector; \
v.VecSector=(v.tmp1< 0)?(7-v.VecSector) :v.VecSector; \
\
if (v.VecSector==1 || v.VecSector==4) \
{ v.Ta= v.tmp2; \
v.Tb= v.tmp1-v.tmp3; \
v.Tc=-v.tmp2; \
} \
\
else if(v.VecSector==2 || v.VecSector==5) \
{ v.Ta= v.tmp3+v.tmp2; \
v.Tb= v.tmp1; \
v.Tc=-v.tmp1; \
} \
\
else \
{ v.Ta= v.tmp3; \
v.Tb=-v.tmp3; \
v.Tc=-(v.tmp1+v.tmp2); \
} \
