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]  in IEEE 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.

Robust sampled-data H (infinity) control for vehicle active suspension systems / Huijun, Gao in IEEE Transactions on control systems technology, Vol. 18 N° 1 (Janvier 2010) 

Public ISBD [article]  in IEEE Transactions on control systems technology > Vol. 18 N° 1 (Janvier 2010) . - pp. 238-245 Titre : Robust sampled-data H (infinity) control for vehicle active suspension systems Type de document : texte imprimé Auteurs : Huijun, Gao, Auteur ; Weichao Sun, Auteur ; Peng, Shi, Auteur Année de publication : 2011 Article en page(s) : pp. 238-245 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : Active  suspension  system  Convex  polytope  H  (infinity)  control  Parameter  uncertainty  Sampled-data  control Index. décimale : 629.1 Résumé : This brief investigates the problem of robust sampled-data H ∞ control for active vehicle suspension systems. By using an input delay approach, the active vehicle suspension system with sampling measurements is transformed into a continuous-time system with a delay in the state. The transformed system contains non-differentiable time-varying state delay and polytopic parameter uncertainties. A Lyapunov functional approach is employed to establish the H ∞ performance, and the controller design is cast into a convex optimization problem with linear matrix inequality (LMI) constraints. A quarter-car model is considered in this brief and the effectiveness of the proposed approach is illustrated by a realistic design example.
