“…Due to the wide applications in many practical systems especially in mechanical systems, the second-order multi-agent systems have been investigated deeply. Many interesting works, such as Hong, Hu, and Gao (2006), Hu and Hong (2007), Gao, Zhang, and Chen (2012), Gao, Zhu, and Chen (2012), Zhang, Chen, and Yu (2012) and Pan, Nian, and Guo (2012), have discussed the second-order consensus. Recently, the high-order consensus problems have been investigated (Ni & Cheng, 2010;Ni, Xiong, & Yang, 2013;Seo, Shim, & Back, 2009;Wang et al, 2011;Xiao & Wang, 2007, Cheng, Hou, & Tan, 2014 have been investigated.…”
