Design of a semi-active knee prosthesis
2009 IEEE International Conference on Robotics and Automation, 2009Current state-of-the-art prostheses for transfemoral amputees operate exclusively through controlled damping or through fully powered gait imitation. The passive devices cannot restore a natural gait, and the active devices are large and inefficient. This paper summarizes the design of a new semi-active prosthetic knee that combines the proven safety ...

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.

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 ...

Active control systems rely entirely on external power to operate the actuators and supply the control forces. In many applications, such systems require a large power source, which makes them costly (this is why there has been very few cars equipped with fully active suspensions) and vulnerable to power failure (this is why the civil engineering ...

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 ...

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.

Fuzzy semi-active damping force estimator (fSADE) and skyhook semi-active suspension systems
International Journal of Vehicle Systems Modelling and Testing, 2011This paper presents the comparative study on semi-active suspension controlled by skyhook algorithm and fuzzy semi-active damping force estimator (fSADE). The damping element used in the semi-active suspension is non-pressurised magnetorheological (MR) damper.

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 ...
