One drawback of the DFC is known as the odd number limitation; that is, DFC can never stabilize a target unstable fixed point of a chaotic discrete-time system, if the Jacobian of its linearized system around the unstable fixed point has an odd number of real eigenvalues greater than unity. To overcome it, in this paper we propose a dynamic DFC method using output measurements of the chaotic systems. The proposed dynamic DFC is realized by using an output feedback controller with a minimal-order observer that has the least order for estimating the state of the chaotic system from the control input and the output measurements. In addition to the design procedure of the controller, we derive a necessary and sufficient condition for the existence of such controllers.<\/jats:p>","DOI":"10.1142\/s0218127402004899","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T11:05:54Z","timestamp":1027767954000},"page":"1047-1055","source":"Crossref","is-referenced-by-count":16,"title":["DELAYED FEEDBACK CONTROL WITH A MINIMAL-ORDER OBSERVER FOR STABILIZATION OF CHAOTIC DISCRETE-TIME SYSTEMS"],"prefix":"10.1142","volume":"12","author":[{"given":"SHIGERU","family":"YAMAMOTO","sequence":"first","affiliation":[{"name":"Department of Systems and Human Science, Osaka University, Toyonaka, Osaka 560-8531, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TORU","family":"HINO","sequence":"additional","affiliation":[{"name":"Department of Systems and Human Science, Osaka University, Toyonaka, Osaka 560-8531, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TOSHIMITSU","family":"USHIO","sequence":"additional","affiliation":[{"name":"Department of Systems and Human Science, Osaka University, Toyonaka, Osaka 560-8531, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","first-page":"2493","volume":"7","author":"Bielawski S.","journal-title":"Phys.
