Until this decade, the complexity inherent in chaotic dynamical systems made control of these systems to simpler states seem unattainable. The realization that chaotic attractors contain many (infinity) unstable periodic orbits led to the notion of chaos control, in which a system could be controlled about one periodic orbit or, in many cases, multiple periodic orbits. Many experimental systems haved been controlled with a variety of chaos control schemes since the first report of experimental control in 1990.
The CRG has been working on application of chaos control techniques to the following of its experimental systems: fluidized beds, bubbling columns, thermal pulse combustors and internal combustion engines.
(1999-08-31) On 1999-07-13, a patent was awarded for Stuart Daw's work with the Ford Motor Company on a "Method of controlling cyclic variation in engine combustion". You may view the patent at the United States Patent and Trademark Office or download a PDF file from our site at this link (1133367 bytes).
Primary contacts for this research area are: C.S. Daw and M.B. Kennel.
