Summary

Chaos is observed as an unpredictable phenomenon due to its sensitivity to initial states. It is a kind of steady-state but locally unstable behavior, and exhibits irregular properties. Such random-like phenomenon is normally regarded as unstable operation which results in additional loss, and therefore is a harmful behavior. Various control methods have been proposed to stabilize the chaotic behavior, such as the Ott-Grebogi-Yorke (OGY) method, the time-delay feedback method, the non-feedback method, the proportional feedback method, the nonlinear control method, the adaptive control method, the neutral networks method, and the fuzzy control method. This chapter discusses various control approaches, including the time-delay feedback control, the nonlinear feedback control, the backstepping control, the dynamic surface control and the sliding mode control, are introduced to stabilize the chaos that occurs in both DC and AC drive systems.
