Kalman Filter Virtual Lab

Kalman Filter virtual laboratory with interactive exercises to study linear and extended Kalman filter design

Kalman Filter Virtual Lab

The Kalman Filter virtual laboratory contains interactive exercises that let you study linear and extended Kalman filter design for state estimation of a simple pendulum system. The virtual lab lets you visualize pendulum dynamics using 3D simulations and animations (see below).

The lab solutions are available upon instructor request. If you would like to request solutions, find an issue, or have a suggestion, contact us here.

Learning Goals

• Simulate a simple pendulum and visualize its swing motion
• Simulate sensor meaurement and compare measured to actual pendulum response
• Design a Kalman Filter to estimate the angular position of the pendulum
• Design an Extended Kalman Filter to estimate the angular position of the nonlinear pendulum system

Setup

To get started with the Kalman filter virtual lab, double-click the project.prj file inside MATLAB®. This will set up the parameters required for simulating the pendulum system and open up a live script, where you'll find the instructions for running the interactive exercises to complete the virtual lab.
