## Abstract

This review describes a procedure for stabilizing a desirable chaotic orbit embedded in a chaotic attractor of dissipative dynamical systems by using small feedback control. The key observation is that certain chaotic orbits may correspond to a desirable system performance. By carefully selecting such an orbit, and then applying small feedback control to stabilize a trajectory from a random initial condition around the target chaotic ol bit, desirable system performance can be achieved. As applications, three examples are considered (1) synchronization of chaotic systems; (2) conversion of transient chaos into sustained chaos; and (3) controlling symbolic dynamics for communication. The first and third problems ave potentially relevant to communication in engineering, and the solution of the second problem can be applied to electrical power systems to avoid catastrophic event such as the voltage collapse.
