## Overview

**Monday:** Observability and Observers (Slides, MP3)

This lecture introduces the concept of observability and the use of estimators for linear systems. Observability is defined as the ability to determine the system state from the (past) time history of measurements. The observability matrix test is given to check if a linear system is observable, and the test is applied to an example. The concept of (linear) observer design is introduced and the ability to arbitrarily place eigenvalues of the closed loop observer error dynamics is related to observability. A cart and pendulum system is used as an example.
