Abstract:Controlling a strange attractor, or say, a chaotic attractor, is introduced
in this chapter. Because of the importance to control the undesirable behavior in
systems, researchers are investigating the use of linear and nonlinear controllers
either to get rid of such oscillations (in power systems) or to match two chaotic
systems (in secure communications). The idea of using the fuzzy logic concept for
controlling chaotic behavior is presented. There are two good reasons for using
the fuzzy control: first, mathematical model is not required for the process, and
second, the nonlinear controller can be developed empirically, without complicated
mathematics. The two systems are well-known models, so the first reason is not a
big deal, but we can take advantage from the second reason.
