Multi-axial Active Isolation for Seismic Protection of Buildings
… structures against seismic hazards. Passive base isolation is one of the common structural control techniques used to enhance the performance of structures subjected to severe earthquake excitations. Isolation bearings employed at the base of a structure naturally increase its flexibility, but …

Power Regeneration in Actively Controlled Structures
The power requirements imposed on an active vibration isolation system are quite important to the overall system design. In order to improve the efficiency of an active isolation system we analyze different feedback control strategies which will provide electrical energy regeneration. The active …

A Thermal Enclosure Prototype For A Suspended Inertial Sensor
… detect merger of more massive objects. Hence, an isolation system is required to reduce the seismic noise. As a part of isolation system (which can be a passive or an active isolation), inertial sensors play an important role in monitoring the seismic vibration and disturbances. However, these …

Dynamics and Control for Vibration Isolation Design
… is the most widely used model for vibration isolation systems. The SDOF system is a simple but worthy model because it quantifies many results of an isolation system. For instance, a SDOF model predicts that the high frequency transmissibility increases when the isolator has passive damping …

Semi-active damping control for vibration isolation of base disturbances
This thesis is concerned with semi-active damping control for vibration isolation of base disturbances. The aim is to investigate the effectiveness and suitability of semi-active damping control strategies for improving steady-state vibration isolation. A single-degree-of-freedom (SDOF) system, …
