The moving mesh method is originally designed for use in the adaptive numerical solution of partial differential equations, where a high proportion of mesh points are placed in the regions of large solution variations and few points in the rest of the domain. In this work, the positions of the aircraft are considered as mesh nodes connected to form a triangular mesh in two spatial dimensions. The outer aircraft positions are planned with the reference point algorithm. This logic provides the outer agents moving point positions that are relative to a virtual point position with the desired heading angle and velocity. The inner agents, or interior mesh nodes, are moved with a moving mesh technique to keep the whole mesh as uniform as possible. The moving mesh technique has built-in mechanisms to keep the mesh as uniform as possible and prevent nodes from crossing over or tangling. This property can be seen as an automatic internal collision avoidance mechanism. It also has explicit formulas for nodal velocities, making the technique easy to implement on computer. The mesh nodes are replaced by unmanned aerial systems with nonlinear six degrees of freedom dynamics. The centralized moving mesh guidance is complimented by a decentralized nonlinear predictive controller to control each aircraft. To validate flexibility and coherency of agents and formation, the moving point concept is used in the simulation to follow an arbitrary, linear, sinewave-like, or curvature shaped flight segments. Robustness of the algorithm is also verified where agents were affected by external wind.<\/jats:p>","DOI":"10.1142\/s2301385016500084","type":"journal-article","created":{"date-parts":[[2016,11,3]],"date-time":"2016-11-03T03:25:15Z","timestamp":1478143515000},"page":"227-244","source":"Crossref","is-referenced-by-count":3,"title":["Guidance of Multi-Agent Fixed-Wing Aircraft Using a Moving Mesh Method"],"prefix":"10.1142","volume":"04","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3615-6731","authenticated-orcid":false,"given":"A Ram","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Aerospace Engineering, University of Kansas, Lawrence, KS 66045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shawn","family":"Keshmiri","sequence":"additional","affiliation":[{"name":"Department of Aerospace Engineering, University of Kansas, Lawrence, KS 66045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weizhang","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Mathematics, University of Kansas, Lawrence, KS 66045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gonzalo","family":"Garcia","sequence":"additional","affiliation":[{"name":"Department of Aerospace Engineering, University of Kansas, Lawrence, KS 66045, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2016,11,2]]},"reference":[{"key":"S2301385016500084BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/TCST.2011.2167331"},{"key":"S2301385016500084BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2012.2235391"},{"key":"S2301385016500084BIB009","doi-asserted-by":"publisher","DOI":"10.1145\/37402.37406"},{"key":"S2301385016500084BIB010","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2005.864190"},{"key":"S2301385016500084BIB011","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2008.2010897"},{"key":"S2301385016500084BIB017","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4419-7916-2"},{"key":"S2301385016500084BIB018","doi-asserted-by":"publisher","DOI":"10.1006\/jcph.2001.6945"},{"key":"S2301385016500084BIB019","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcp.2015.08.032"},{"key":"S2301385016500084BIB021","doi-asserted-by":"publisher","DOI":"10.1007\/s10846-010-9481-0"},{"key":"S2301385016500084BIB022","doi-asserted-by":"publisher","DOI":"10.1109\/TAES.2012.6178048"},{"key":"S2301385016500084BIB024","doi-asserted-by":"crossref","first-page":"1657","DOI":"10.1002\/rnc.3037","volume":"23","author":"Garcia G.","year":"2013","journal-title":"Wiley Int.
