Detailed Description

Function prototypes for Adaptive Optics Control loop engine predictive control.

AO engine uses stream data structure

Function Documentation

__attribute__()

void __attribute__

(

(constructor)

)

Initialize module.

AOloopControl_PredictiveControl_builPFloop_WatchInput()

imageID AOloopControl_PredictiveControl_builPFloop_WatchInput	(	long	loop,
		long	PFblock,
		long	PFblockStart,
		long	PFblockEnd,
		long	NBbuff
	)

Purpose

Listens to real-time telemetry streams buffers aol<loop>_modeval_ol_logbuff0 and aol<loop>_modeval_ol_logbuff1

When new buffer is complete, extract the requested values from it and write to aol<loop>_modevalol_PFb<PFblock>

Arguments

Parameters

[in]	loop	LONG loop index
[in]	PFblock	LONG Block number
[in]	PFblockStart	LONG Block start index
[in]	PFblockEnd	LONG Block end index

#param[in] NBbuff LONG Number of input buffers to merge for each output

AOloopControl_PredictiveControl_mapPredictiveFilter()

errno_t AOloopControl_PredictiveControl_mapPredictiveFilter	(	const char *	IDmodecoeff_name,
		long	modeout,
		double	delayfr
	)

AOloopControl_PredictiveControl_setPFsimpleAve()

imageID AOloopControl_PredictiveControl_setPFsimpleAve	(	char *	IDPF_name,
		float	DecayCoeff
	)

Set predictive filter to simple average of previous measures.

DecayCoeff is betweeen 0 and 1 1 : no decay, pure average

This is used to give more weigth to most recent measurements

AOloopControl_PredictiveControl_testPredictiveFilter()

double AOloopControl_PredictiveControl_testPredictiveFilter	(	const char *	IDtrace_name,
		long	modeout,
		double	delayfr,
		long	filtsize,
		const char *	IDfilt_name,
		double	SVDeps
	)

predictive control based on SVD

input: mode values trace [ii: time, jj: mode number] mode index delayfr [delay in frame unit] filtsize [number of samples in filter]
