hpm_mcl_filter_pll_type_i()

void hpm_mcl_filter_pll_type_i	(	mcl_filter_pll_type_i_t *	pll,
		float	sin_val,
		float	cos_val,
		mcl_filter_pll_output_t *	output
	)

Type I Phase-Locked Loop (PLL) Filter. This function processes the input signal to estimate the phase and speed of the signal.

Parameters

pll	Pointer to the mcl_filter_pll_type_i_t structure, containing the internal state and configuration of the PLL.
sin_val	The sine component of the input signal, used for phase difference calculation.
cos_val	The cosine component of the input signal, used for phase difference calculation.
output	Pointer to the mcl_filter_pll_output_t structure, for storing the output results including theta and speed.

hpm_mcl_filter_pll_type_ii()

void hpm_mcl_filter_pll_type_ii	(	mcl_filter_pll_type_ii_t *	pll,
		float	sin_val,
		float	cos_val,
		mcl_filter_pll_output_t *	output
	)

Type II Phase-Locked Loop (PLL) Filter. This function updates the PLL state based on the input sine and cosine values and calculates the output theta and speed.

Parameters

pll	Pointer to the PLL structure containing the state and configuration parameters.
sin_val	The sine value of the input signal, representing the sine component.
cos_val	The cosine value of the input signal, representing the cosine component.
output	Pointer to the output structure to store the computed theta and speed.
