“…The maximum force that an MRFD can deliver depends on the properties of MRFs, their flow pattern, and the size of the damper. This device also offers highly reliable operation at a modest cost and its performance is in the development of appropriate control algorithm that can take advantage of the unique characteristics of the device 51 . For increasing the safety and reliability of any static and dynamic systems, the vibration control strategies and developments in controllable actuators is important.…”

Vibration isolation and control of structures subjected to different types of dynamic loads due to periodic forces, impact and shock type forces and earthquake forces is an important area in structural engineering. The structures can be machine foundations, buildings, bridges, towers, automobiles, ship structures, military tanks and aeronautical structures. Some of these devices used are elastic springs, viscoelastic dampers, viscous fluid dampers, magnetorheological dampers and friction dampers. This article gives latest developments in vibration control of structures and structural components using magnetorheological fluids. The current status of technology and further research requirements to be studied in these areas are highlighted.Keywords: Automobile brakes, magnetorheological fluids, structure and structural components, suspension systems, vibration control.IMPROVEMENT in manufacturing technology has provided machines of higher ratings, longer bridges, taller buildings which requires to satisfy the static, dynamic capacity and serviceability and stability limits for members/ systems prescribed by codes of practice. These machines/ structures give rise to considerable higher dynamic forces and thereby higher stresses. This demands development of advanced control and safety systems to keep the structural members/systems static and dynamic responses within tolerable levels. The performance, safety and stability of structures supporting the machines/structures depend largely on their design of suspension systems and their interaction with the environment. In this article, current status of technology in development of magnetorheological and friction dampers and their use in vibration control of structural and structural components in different fields of engineering applications are presented.

The polynomial matrix using the block coefficient matrix representation auto-regressive moving average (referred to as the PM-ARMA) model is constructed in this paper for actively controlled multi-degree-of-freedom (MDOF) structures with time-delay through equivalently transforming the preliminary state space realization into the new state space realization. The PM-ARMA model is a more general formulation with respect to the polynomial using the coefficient representation auto-regressive moving average (ARMA) model due to its capability to cope with actively controlled structures with any given structural degrees of freedom and any chosen number of sensors and actuators. (The sensors and actuators are required to maintain the identical number.) under any dimensional stationary stochastic excitation.
