RETRACTED: Synchronization and state feedback control of linearly coupled singular systems

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).The Editor-in-Chief of Applied Mathematics and Computation has decided to retract the article “Synchronization and state feedback control of linearly coupled singular systems” by Fang Qingxiang, published in Volume 232 (2014), pages 381–390. The retraction of this article has been requested by the author, due to significant similarities between this article and the article “Synchronization and Control of Linearly Coupled Singular Systems” by Fang Qingxiang, Peng Jigen and Cao Feilong, previously published in Mathematical Problems in Engineering, Volume 2013 (2013), Article ID 230741, pages 1–10, DOI: http://dx.doi.org/10.1155/2013/230741.
