Input-delayed control of uncertain seat suspension systems with human-body model / Huijun, Gao in IEEE Transactions on control systems technology, Vol. 18 N° 3 (Mai 2010)  

Public ISBD [article]  inIEEE Transactions on control systems technology > Vol. 18 N° 3 (Mai 2010) . - pp. 591-601 Titre : Input-delayed control of uncertain seat suspension systems with human-body model Type de document : texte imprimé Auteurs : Huijun, Gao, Auteur ; Yingbo Zhao, Auteur ; Weichao Sun, Auteur Année de publication : 2011 Article en page(s) : pp. 591-601 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : Human body Input delay Multi-objective control Parameter uncertainty Seat suspension Index. décimale : 629.1 Résumé : This paper deals with the problem of input-delayed robust H?? state-feedback controller design for a class of semi-active seat suspension systems with parameter uncertainties and actuator time delays. A vertical vibration model of human body is employed and put together with the plant of the seat suspension system. The controller design is cast into a convex multi-objective optimization problem with linear matrix inequality (LMI) constraints by defining a Lyapunov functional and using the delay partitioning method. The usefulness and advantages of the proposed controller design methodology are demonstrated through a design example.
