| __STATIC_INLINE void | arm_inv_clarke_f32 (float32_t Ialpha, float32_t Ibeta, float32_t *pIa, float32_t *pIb) |
| Floating-point Inverse Clarke transform. | |
| __STATIC_INLINE void | arm_inv_clarke_q31 (q31_t Ialpha, q31_t Ibeta, q31_t *pIa, q31_t *pIb) |
| Inverse Clarke transform for Q31 version. | |
Inverse Clarke transform converts the two-coordinate time invariant vector into instantaneous stator phases.
The function operates on a single sample of data and each call to the function returns the processed output. The library provides separate functions for Q31 and floating-point data types.
pIa and pIb are the instantaneous stator phases and Ialpha and Ibeta are the two coordinates of time invariant vector. | __STATIC_INLINE void arm_inv_clarke_f32 | ( | float32_t | Ialpha, |
