C-library with implementation of the various space-vector transformations

This embedded C-library provides the various types of space-vector transformation:

Clarke transformations
- Forward full (ABC to Alpha-Beta)
- Forward reduce (AB to Alpha-Beta) in case when A + B + C = 0
- Backward (Inverse) full (Alpha-Beta to ABC)
- Backward (Inverse) reduce (Alpha-Beta to AB) in case when A + B + C = 0
Park transformations
- Forward (Alpha-Beta to DQ)
- Backward (Inverse) (DQ to Alpha-Beta)

HowToUse (example)

Example 1 - Inverse Full Clarke transformation

  #include "vector_transfs.h"

  // updatable user variables:
  float al, be, a, b, c;
  		
  // 1st step: create and initialize the global variable of user data structure
  tIFClarke sIFClarke = IF_CLARKE_DEFAULTS;

  // 2nd step: Next code must be executed every time a new calculation of a, b, c is needed
  sIFClarke.fAl = al;               // set Alpha input
  sIFClarke.fBe = be;               // set Beta input
  sIFClarke.m_albe2abc(&sIFClarke); // call the Inverse Full Clarke transformation function
  a = sIFClarke.fA;                 // update the a variable
  b = sIFClarke.fB;                 // update the b variable
  c = sIFClarke.fC;                 // update the c variable

Example 2 - Forward Park transformation

  #include "vector_transfs.h"
  #include <math.h>

  // updatable user variables:
  float al, be, d, q, angle;
  		
  // 1st step: create and initialize the global variable of user data structure
  tFPark sFPark = F_PARK_DEFAULTS;

  // 2nd step: Next code must be executed every time a new calculation of d, q is needed
  sFPark.fAl = al;                  // set Alpha input
  sFPark.fBe = be;                  // set Beta input
  sFPark.fSinAng = sinf(angle);     // calculate sine
  sFPark.fCosAng = cosf(angle);     // calculate cosine
  sFPark.m_albe2dq(&sFPark);        // call the Forward Park transformation function
  d = sIFClarke.fD;                 // update the d variable
  q = sIFClarke.fQ;                 // update the q variable
