A four-wing chaotic attractor is observed numerically. This attractor, however, is shown to be an numerical artifact by further theoretical analysis and analog circuit experiment. The observed four-wing attractor actually has two coexisting (upper and lower) attractors, which appear simultaneously and are located arbitrarily closely in the phase space. By introducing a simple linear state-feedback control term, some symmetries of the system and similarities of the linearized characteristics can be destroyed, thereby leading to the appearance of some diagonal and anti-diagonal periodic orbits, through which the upper and lower attractors can indeed be merged together to form a truly single four-wing chaotic attractor. This four-wing attractor is real; it is further confirmed analytically, numerically, as well as electronically in the paper. Moreover, by introducing a sign-switching control function, the system orbit can be manipulated so as to switch between two equilibria or among four equilibria, generating two one-side double-wing attractors, which can also be merged to yield a real four-wing attractor. <\/jats:p>","DOI":"10.1142\/s0218127406015180","type":"journal-article","created":{"date-parts":[[2006,6,16]],"date-time":"2006-06-16T10:44:54Z","timestamp":1150454694000},"page":"859-885","source":"Crossref","is-referenced-by-count":62,"title":["FOUR-WING ATTRACTORS: FROM PSEUDO TO REAL"],"prefix":"10.1142","volume":"16","author":[{"given":"GUOYUAN","family":"QI","sequence":"first","affiliation":[{"name":"Department of Automation, Tianjin University of Science and Technology, Tianjin 300222, P.
