Under the condition that all the nominal isolated subsystems have uniform relative degree, the considered class of interconnected systems is transferred to a new interconnected system formed of single input systems, which facilitates the decentralised control design. A new term, weak mismatched uncertainty, is introduced for the first time to recognise a class of mismatched uncertainties in the isolated subsystems. The study shows that the effects of both matched and weak mismatched uncertainties in the isolated subsystems can be rejected completely by appropriate choice of control, and the effects of matched interconnections can be largely reduced if the control gain is sufficiently high. date: 2016-07-26 date_type: published official_url: http://doi.org/10.1016/j.ifacol.2016.07.518 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Journal Article verified: verified_manual elements_id: 1195556 doi: 10.1016/j.ifacol.2016.07.518 lyricists_name: Spurgeon, Sarah lyricists_id: SSPUR40 actors_name: Spurgeon, Sarah actors_id: SSPUR40 actors_role: owner full_text_status: public publication: IFAC-PapersOnLine volume: 49 number: 9 pagerange: 152-157 issn: 2405-8963 citation: Yan, XG; Spurgeon, SK; Zhao, D; Guo, L; (2016) Decentralised Stabilisation of Nonlinear Time Delay Interconnected Systems.
