چکیده

The overall goal of the research conducted in this paper is to develop next generation force feedback systems by combining novel Magnetorheological (MR) fluid based systems with microstructural analysis and advanced control system design. Two MR fluid based telerobotic systems are designed, prototyped and tested with medical applications. Force feedback control is employed to replicate in the master those forces encountered in the slave. The test results show the appropriate performance of MR fluid based systems used in haptic and force feedback applications.

A magnetorheological fluid damper for robust vibration control of flexible rotor-bearing systems: A comparison between sliding mode and fuzzy approaches

Squeeze Film Dampers (SFD) are commonly used for passive vibration control of rotor-bearing systems. The Magnetorheological (MR) and Electrorheological (ER) fluids in SFDs give a varying damping characteristic to the bearing that can provide active control schemes for the rotor-bearing system. A common way to model an MR bearing is implementing the Bingham plastic model. Adding this model to th...

H∞-PD Controller for Suspension Systems with MR Dampers

In this paper, we consider the implementation of a static H∞ output feedback controller to a quarter vehicle suspension system with a semi-active magnetorheological fluid (MRF) damper. Unlike most of the existing literature, all the states in the equation of motion are relative displacements and velocities between sprung, unsprung masses and road disturbance instead, in addition the input to th...

Hierarchical semi-active control of base-isolated structures using a new inverse model of magnetorheological dampers

Magnetorheological (MR) dampers have received special attention as semi-active devices for mitigation of structural vibrations. Because of the inherent nonlinearity of these devices, it is difficult to obtain a reasonable mathematical inverse model. This paper is concerned with two related concepts. On one hand, it presents a new inverse model of MR dampers based on the normalized Bouc–Wen mode...

Seismic Responses of Civil Structures under Magnetorheological-device Direct Control

This paper presents an efficient control strategy for magnetorheological (MR) dampers embedded in building structures to mitigate quake-induced vibrations. In this work, MR dampers are used as semi-active devices, taking the advantages of the fail-safe operation and low power requirement. By using a static hysteresis model for the MR damper, a suitable controller is proposed here for direct con...
