Function Documentation

precision_pi_init()

void precision_pi_init	(	struct precision_pi *	pi,
		double	kp,
		double	ki )

#include <precision_pi.h>

Initialize a PI controller.

Parameters

pi	Controller instance.
kp	Proportional gain.
ki	Integral gain.

precision_pi_reset()

void precision_pi_reset

(

struct precision_pi *

pi

)

#include <precision_pi.h>

precision_pi_update()

double precision_pi_update	(	struct precision_pi *	pi,
		double	error )

#include <precision_pi.h>

Update a PI controller from an error sample.

Parameters

pi	Controller instance.
error	Current control error.

Returns

Controller output.
