Semi-active Iterative Learning Control
Proceedings of the 2011 American Control Conference, 2011This paper presents an Iterative Learning Control (ILC) algorithm for iterative parameter update in a semi-active system. The ILC law is designed to minimize a cost function, for example, the mean squared tracking error. First, a parametrized lifted domain representation of a linear parameter-varying system is developed explicitly. Based on this lifted

Experimental Comparison of Passive, Semi-Active On/Off, and Semi-Active Continuous Suspensions
SAE Technical Paper Series, 1989<div class="htmlview paragraph">Much computer simulation work has been conducted on various kinds of semi-active suspensions composed of linear components and linear damping. These results show broad improvements over passive suspensions, but there has been little experimental data for verification.

International Journal of Computer Applications in Technology, 2011
This paper presents the simulation study of magnetorheological semi-active suspension system controlled by a new proposed algorithm. The control algorithm named as Semi-Active Damping Force Estimator (SADE) is proposed to control the operations of the magnetorheological damper.

Vibration Attenuation by Semi-active Dampers
2013This contribution deals with the optimization of a tractor’s cab’s vertical acceleration. The mathematical model of the simplified system is derived. The acceleration of the chassis is considered as the actuating variable. In the optimization the acceleration of the tractor’s cab is minimized under the constraint of a maximum displacement between the ...

Semi-active RFID Devices for Traceability
2015In this paper a semi-active RFID module for remote monitoring of storage conditions during the transportation is proposed. It integrates one SmartTag and some sensors, and allows also to locate the object to the one which is related. In order to obtain the real time observing on the transportation vehicle an On Board Unit (OBU) is installed that works ...

Volume 3: Biomedical and Biotechnology Engineering, 2014
This paper presents a semi active orthosis designed for recovering the mobility on a paralyzed hand because of a fifth cervical injury, C5. The orthosis is based on a six bar mechanism and a circular slide, using the hand as a part of the mechanism. Other similar devices were developed around the world, nevertheless this design is independent of an ...

Active and Semi-Active Vibration Isolation
Journal of Vibration and Acoustics, 1995In the five decades since the founding of the ASME Design Engineering Division, the important problem of vibration isolation has been attacked first through the design of passive spring-damper suspensions and later by the use of active and semi-active elements.

A semi-active suspension embedded controller in a FPGA
International Symposium on Industrial Embedded System (SIES), 2010This paper explores the applicability of a Piece-Wise Multilinear Fuzzy Inference System (PWM-FIS) to the realization of embedded digital controllers for semi-active suspension systems. The nonlinear controller, obtained by approximation of a modified Skyhook control strategy trough off-line training of the PWM-FIS, has been implemented in a Field ...

Performance characterisation of semi-active RFID technology
International Journal of Radio Frequency Identification Technology and Applications, 2009Thousands of packages arrive at the Department of Defense's supply and transportation hubs and storage sites/depots daily. Packages with passive RFID tags containing military material, pharmaceuticals, medical surgical instruments or regulated hazardous materials arrive integrated with other classes of supply.
