kalman1d_t Struct Reference

One-dimensional Kalman filter state. More...

#include <kalman_filter.h>

Public Attributes
float	x
	State estimate (e.g., pressure).
float	P
	Estimate uncertainty (error covariance).
float	Q
	Process noise covariance.
float	R
	Measurement noise covariance.

Detailed Description

One-dimensional Kalman filter state.

x: Estimated value (state) after the last update. P: Estimated uncertainty (error covariance) of the state. Q: Process noise covariance (uncertainty introduced by the system dynamics). R: Measurement noise covariance (uncertainty in the sensor measurements).
