EKF/UKF Toolbox for Matlab

Simo Särkkä, Jouni Hartikainen, and Arno Solin

Introduction

EKF/UKF is an optimal filtering toolbox for Matlab. Optimal filtering is a frequently used term for a process, in which the state of a dynamic system is estimated through noisy and indirect measurements. This toolbox mainly consists of Kalman filters and smoothers, which are the most common methods used in stochastic state-space estimation. The purpose of the toolbox is not to provide a highly optimized software package, but instead to provide a simple framework for building proof-of-concept implementations of optimal filters and smoothers to be used in practical applications.

Most of the code has been written by Prof. Simo Särkkä. Later Dr. Jouni Hartikainen and Arno Solin documented and extended it with new filters and smoothers as well as simulated examples.

Download and Installation Guide

The software consists of Matlab m-files. Clone or download the latest version and make sure the toolbox directory is included in your Matlab path by addpath path to ekfukf.

Documentation

The documentation demonstrates the use of software as well as state-space estimation with Kalman filters in general. The purpose is not to give a complete guide to the subject, but to discuss the implementation and properties of Kalman filters.

  • Documentation available on GitHub

The methods that are discussed in the current documentation are:

  • Kalman filters and smoothers
  • Extended Kalman filters and smoothers
  • Unscented Kalman filters and smoothers
  • Gauss-Hermite Kalman filters and smoothers
  • Cubature Kalman filters and smoothers
  • Interacting Multiple Model (IMM) filters and smoothers

Useful background information on the methods can also be found in the book:

Demos

There are a number of demonstration programs for the provided filters and smoothers. The code and a short introduction to them are given below. All of the demonstration programs are discussed in the documentation.

Demonstration programs for linear state-space models:

  • 2D CWPA-model, kf_cpwa_demo

Demonstration programs for non-linear state-space models:

  • Tracking a random sine signal, ekf_sine_demo
  • UNGM-model, ungm_demo
  • Bearings only tracking, bot_demo
  • Reentry vehicle tracking, reentry_demo

Demonstration programs for multiple model systems:

  • Tracking a target with simple manouvers, imm_demo
  • Coordinated turn model, ct_demo
  • Bearings only tracking of a manouvering target, botm_demo
