Semi-active Control of Building Structures using Variable Stiffness Device and Fuzzy Logic
Semi-active control devices, also called “Intelligent” control devices, constitute the positive aspects of both the passive and active control devices. A semi-active control strategy is similar to the active control strategy, but this control device has been shown to be more energy-efficient than active devices. A particular type of semi-active control device, the Variable Stiffness Device (VSD...
متن کاملA Bench-top Prototype of a Variable Stiffness Prosthesis
A prototype of a variable stiffness prosthetic joint has been constructed and tested. The joint is based on two actuator subsystems arranged in an antagonistic configuration. Each actuator subsystem is composed of a small, high-speed electric motor, a single stage, worm-gear based transmission and a nonlinear stiffness element. Each nonlinear stiffness element is composed of a set of short sect...
متن کاملA Semi-Active Variable Stiffness and Damping System for Vibration Control of Civil Engineering Structures
This paper proposes a new semi-active variable stiffness and damping system (AVSD) for vibration control of civil engineering structures. The AVSD system can alter rigidity and damping of the controlled structure at each control interval to attenuate the structural responses. The composition of two hydraulic cylinder-piston systems of the AVSD system is capable of amplifying the interstory drif...
متن کاملActive control of a powered ankle-foot prosthesis
Amputees suffer a higher metabolic demand on their bodies. Passive prostheses seek to reduce this deficit through elastic distribution of the energy inherently dissipated in walking. Yet with no capacity to generate torque they lack truly biomimetic function. The active prosthesis is a solution to this and opens up a world of active control in the timing and magnitude of energy return. Being ab...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
