Routines for hysteresis modeling

Function Documentation

hyst_new()

hyst_t* hyst_new	(	real	hysteresis,
		real	alpha,
		real	stroke,
		long	nact
	)

Hysteresis modeling. Create the hysteresis model. It assumes that the hysteresis is measured with a stroke.

Parameters

hysteresis	The ratio of the maximum difference of ascending/descending curve over 2*stroke.
alpha	The alpha parameter
stroke	The DM command is from -stroke to stroke
nact	Number of actuators

hyst_reset()

void hyst_reset

(

hyst_t *

hyst

)

Reset hysteresis state

hyst_free()

void hyst_free

(

hyst_t *

hyst

)

Free hysteresis model.

hyst_dmat()

void hyst_dmat	(	hyst_t *	hyst,
		dmat *	dmreal,
		const dmat *	dmcmd
	)

Apply hysteresis to DM vector. dmreal and dmcmd may be the same

hyst_dcell()

void hyst_dcell	(	hyst_t **	hyst,
		dcell *	dmreal,
		const dcell *	dmcmd
	)

Apply hysteresis to set of DM vectors

hyst_test()

dmat* hyst_test	(	real	hysteresis,
		real	hyst_alpha,
		real	hyst_stroke,
		const dmat *	dmcmd
	)

Test hysteresis model. Dmcmd has dimensions of nact*ntime
