Savaresi, Sergio M., Auteur ; Silani, Enrico, Auteur ; Bittati, Sergio |The problem considered in this paper is the design and analysis of control strategies for semiactive suspensions in road vehicles. The most commonly used control framework is the well-known Sky-Hook (SH) damping. Two-state or linear approximatio[...]

Niu, Yugang, Auteur ; Lam, James, Auteur ; Wang, Xingyu ; Ho, Daniel W. C. |In this paper, the adaptive H∞ control problem based on the neural network technique is studied for a class of strict feedback nonlinear systems with mismatching nonlinear uncertainties that may not be linearly parametrized. By combining the bac[...]

Wang, Shengda, Auteur ; Danai, Kourosh, Auteur ; Wilson, Mark |An adaptive method of helicopter track and balance is introduced to improve the search for the required blade adjustements. In this method, an interval model is used to represent the range of effect of blade adjustements on helicopter vibration,[...]

Zhu, Wen-Hong, Auteur ; Piedboeuf, Jean-Claude, Auteur |An adaptive output force control scheme for hydraulic cylinders is proposed by using direct force measurement through loadcells. Due to the large and somewhat uncertain piston friction force, cylinder chamber pressure control with coulomb-viscou[...]

Chen, H., Auteur ; Liu, Z.-Y., Auteur ; Sun, P.-y. |This paper formulates the active suspension control problem as disturbance attenuation problem with output and control constraints. The H∞ performance is used to measure ride comfort such that more general road disturbances can be considered, wh[...]

Ding, Yu, Auteur ; Zhou, Shiyu, Auteur ; Chen, Yong |Dimensional variation reduction is critical to assure high product quality in discrete part manufacturing. Recent innovations in sensor technology enable in process implementation of laser optical coordinate sensors and continoues monitoring of [...]

Zollo, Loredana, Auteur ; Siciliano, Bruno, Auteur ; Alessandro De Luca ; Guglielmelli, Eugenio ; Dario, Paolo |Studies on motion control of robot manipulators with elastic joints are basically aimed at improving robot performance in tracking or regulation tasks. In the interaction between robot and environment, instead, the main objective of a control st[...]

Fortgang, Joel, Auteur ; Singhose, Wiliam, Auteur |Systems with flexible dynamics often vibrate due to external disturbances, as well as from changes in the reference command. Feedback control is an obvious choice to deal with these vibrations, but in many cases, it is insufficient or difficult [...]

Maithripala, D. H. S., Auteur ; Berg, Jordan M., Auteur ; Dayawansa, W. P. |This paper examines control strategies for electrostatically actuated micro-electro-mechanical systems (MEMS), with the goals of using feasible measurements to eliminate the pull in bifurcation, robustly stabilize and desired operating point in [...]

Yilmaz, Hakan, Auteur ; Stefanopoulou, Anna, Auteur |In this paper we extend an existing crank angle resolved dynamic nonlinear model of a six-cylinder 12 l turbocharged (TC) Diesel engine with exhaust valve closing (EVC) variability. Early EVC achieves a high level of internal exhaust gas recircu[...]

Aswani, D. J., Auteur ; Cook, J. A. ; Grizzle, J. W. ; Van Nieuwstadt, M. J., Auteur |The 2004 Federal Tier II and California LEV I emission standards for diesel light trucks mandate tailpipe NOχ levels of 0.6 g/mi. Active lean NOχ catalyst (ALNC or LNC) have been proposed as a means to achieve this standard. These catalyst requi[...]

Kazantzis, Nikolaos, Auteur ; Chong, K. T., Auteur ; Park, J. H. ; Parlos, Alexander G. |A new time-discretization method for the development of a sampled-data representation of a nonlinear continoues-time input-driven system with time delay is proposed. It is based on the Taylor Lie series expansion method and zero-order hold assum[...]
