Automated stocker system is widely used in semiconductor and liquid crystal display (LCD) industries for handling storage of valuable wafers or glass panels. Massive front opening unified pods (foups) containing wafers, cassettes storing panels, are placed shelf stockers during manufacturing. Although several preventative measures have been taken, the past earthquakes, substantial financial los...

An optimal semi-active Cuckoo- Fuzzy algorithm is developed to drive the hydraulic semi-active damper for effective control of the dynamic deformation of building structures under earthquake loadings, in this paper. Hydraulic semi-active dampers (MR dampers) are semi active control devices that are managed by sending external voltage supply. A new adaptive fuzzy logic controller (FLC) is introd...

This paper is concerned with a new fully adaptive control scheme for vibration isolation using a semi-active MR damper installed between ground and first floor, which is composed of two adaptive controllers. One is an adaptive inverse controller which can give necessary input voltage to MR damper so as to generate specified reference damping force to be acted on a controlled structure. The inpu...

This paper investigates the use of inerters for vibration suppression of a multistorey building structure. The inerter was proposed as a two-terminal replacement for the mass element, with the property that the applied force is proportional to the relative acceleration across its terminals. It completes the force-current mechanical-electrical network analogy, providing the mechanical equivalent...

The purpose of this paper is to present a new modified parametric algebraic model for MR damper in controlling the semi-active suspension system. Except for its accuracy, modified algebraic model is additionally more preferable in terms of its low computational expenses compared to differential modified Bouc-Wen’s model that is extremely computationally demanding. The control part consists of t...

Semi-active dampers utilizing various working principles have been developed for a variety of vehicles. These semi-active dampers have been designed to resolve the ride and handling compromise associated with conventional passive dampers, and increase vehicle stability. This thesis briefly reviews existing semi-active damper designs, including but not limited to MR dampers, before presenting tw...

Building structures are vulnerable to the shocks caused by earthquakes. Buildings that have been destroyed an earthquake very detrimental in terms of material loss and mental trauma. However, technological developments now enable us anticipate from earthquakes minimize losses. One technologies has used, is currently being further developed, a damping device fitted building structure. There vari...

Magnetorheological (MR) dampers have received a great deal of attention due to their being a potential technology to conduct semi-active vibration control and it has become vitally important to describe the dynamic responses of these devices in an effective manner in order to develop successful control algorithms. To this end, a considerable effort has been devoted in the literature to study th...

-The performance of fuzzy logic (FLC) and PID controllers optimized by particle swarm optimization (PSO) for semi-active suspension system using magneto-rheological (MR) damper are investigated. MR damper is an intelligent damper filled with particle magnetic polarizable and suspended into a liquid form. The Bouc-Wen model of MR damper is used to determine the required damping force based on fo...
