kalman_filter_init()

void kalman_filter_init

(

)

A Kalman-filter based servo. This module implements the Kalman-filter introduced in the paper: 'Performance Analysis of Kalman-Filter-Based Clock Synchronization in IEEE 1588 Networks' by Giada Gorgi and Claudio Narduzzi (https://ieeexplore.ieee.org/document/5934411) Initialize the Kalman-filter.
