# Lecture: Dynamic Behavior

From FBSwiki

Prev: ODEs | Chapter 4 | Lecture Index | Next: Linear Systems |

## Overview

This lecture provides an introduction to the behavior of (nonlinear) dynamical systems. Formal definitions of stability are given and phase portraits are introduced to help visualize the concepts. Local and global behavior of nonlinear systems is discussed, using a damped pendulum and the predator-prey problem as examples. Performance of control systems is presented for transient and steady state specifications. </font>
