Function Documentation

hpm_mcl_clc_run()

hpm_mcl_stat_t hpm_mcl_clc_run	(	mcl_hw_loop_t *	loop,
		float	d_expect,
		float	q_expect
	)

Run CLC (Current Loop Controller) hardware acceleration.

This function performs current loop control using hardware CLC module. It calculates d-q axis voltage outputs based on expected and actual current values.

Parameters

loop	Pointer to hardware loop structure
d_expect	Expected d-axis current reference
q_expect	Expected q-axis current reference

Returns

mcl_success if operation successful, error code otherwise

hpm_mcl_hw_loop_init()

hpm_mcl_stat_t hpm_mcl_hw_loop_init	(	mcl_hw_loop_t *	loop,
		mcl_hw_loop_cfg_t *	cfg
	)

Initialize hardware loop components.

This function initializes the hardware loop components including VSC, CLC, and QEO modules. Each component is initialized through callback functions if they are configured.

Parameters

loop	Pointer to hardware loop structure
cfg	Pointer to hardware loop configuration

Returns

mcl_success if initialization successful, error code otherwise

hpm_mcl_qeo_run()

hpm_mcl_stat_t hpm_mcl_qeo_run

(

mcl_hw_loop_t *

loop

)

Run QEO (Quadrature Encoder Output) hardware acceleration.

This function performs inverse Park and inverse Clarke transformations using hardware QEO module. It converts d-q voltages to three-phase PWM duty cycles.

Parameters

loop	Pointer to hardware loop structure

Returns

mcl_success if operation successful, error code otherwise

hpm_mcl_vsc_run()

hpm_mcl_stat_t hpm_mcl_vsc_run

(

mcl_hw_loop_t *

loop

)

Run VSC (Vector Signal Controller) hardware acceleration.

This function performs Clarke and Park transformations using hardware VSC module. It converts three-phase currents (ia, ib, ic) to alpha-beta and d-q coordinates.

Parameters

loop	Pointer to hardware loop structure

Returns

mcl_success if operation successful, error code otherwise
