Application of adaptive wavelet networks for vibration control of base isolated structures
Karimi, Hamid Reza; Zapateiro, Mauricio; Luo, Ningsu (Journal article; Peer reviewed, 2010)This paper presents an application of wavelet networks (WNs) in identification and control design for a class of structures equipped with a type of semiactive actuators, which are called magnetorheological (MR) dampers. ... -
Feedback vibration control of a base-isolated building with delayed measurements using h∞ techniques
Karimi, Hamid Reza; Zapateiro, Mauricio; Luo, Ningsu; Rossell, Josep M. (Journal article; Peer reviewed, 2010)n this paper we address the problem of vibration reduction of buildings with delayed measurements, where the delays are time-varying and bounded. We focus on a convex optimization approach to the problem of state-feedback ... -
Frequency domain control based on quantitative feedback theory for vibration suppression in structures equipped with magnetorheological dampers
Zapateiro, Mauricio; Karimi, Hamid Reza; Luo, Ningsu; Spencer, Billie F Jr (Journal article; Peer reviewed, 2009)This paper addresses the problem of designing quantitative feedback theory (QFT) based controllers for the vibration reduction in a structure equipped with an MR damper. In this way, the controller is designed in the ... -
Landing gear suspension control through adaptive backstepping techniques with H∞ performance
Zapateiro, Mauricio; Pozo, Francesc; Rossell, Josep M.; Karimi, Hamid Reza; Luo, Ningsu (Chapter; Peer reviewed, 2011)Landing gear suspension systems fulfill the tasks of absorbing the vertical energy of the touch-down as well as providing passenger and crew comfort with a smooth ground ride before take-off and after landing. They are ... -
A linear matrix inequality approach to robust fault detection filter design of linear systems with mixed time-varying delays and nonlinear perturbations
Karimi, Hamid Reza; Zapateiro, Mauricio; Luo, Ningsu (Journal article; Peer reviewed, 2010)In this paper, the problem of robust fault detection filter (RFDF) design for a class of linear systems with some nonlinear perturbations and mixed neutral and discrete time-varying delays is investigated. By using a ... -
An LMI approach to quantized H∞ control of uncertain linear systems with network-induced delays
Karimi, Hamid Reza; Luo, Ningsu; Zapateiro, Mauricio (Chapter; Peer reviewed, 2010)his paper deals with a convex optimization approach to the problem of robust network-based Hinf control for linear systems connected over a common digital communication network with norm-bounded parameter uncertainties. ... -
Semiactive control methodologies for suspension control with magnetorheological dampers
Zapateiro, Mauricio; Pozo, Francesc; Karimi, Hamid Reza; Luo, Ningsu (Journal article; Peer reviewed, 2012)Suspension systems are one of the most critical components of transportation vehicles. They are designed to provide comfort to the passengers to protect the chassis and the freight. Suspension systems are normally provided ... -
Vibration control of base-isolated structures using mixed H-2/H-infinity output-feedback control
Karimi, Hamid Reza; Zapateiro, Mauricio; Luo, Ningsu (Journal article; Peer reviewed, 2009)A mixed H-2/H-infinity output-feedback control design methodology for vibration reduction of base-isolated building structures modelled in the form of second-order linear systems is presented. Sufficient conditions for the ...
