Semi-active and Active Control of an ERF Embedded in Pneumatic Vibration Isolator
In the paper, the Electrorheological fluid(ERF) is embedded in the pneumatic vibration isolator and three kinds of control systems are designed, which experimental results are also compared. The first kind of the control system is the semi-active control system, which is designed for ERF controllable damper. The second kind of the control system is the active control system, which is designed f...

متن کاملHomogeneous Electrorheological Fluids Applied to Vibration Control
The purpose Electrorheological (ER) fluids are capable of providing continuously variable damping forces in response to an electrical stimulus. Many prototype ER dampers, described in the literature, have been based upon exploiting the variable shear properties of ER fluids. Recently, an alternative mode of operation, namely squeeze-flow, has been identified and investigated. Furthermore, most ...
متن کاملThe Development of an Intelligent Hybrid Active-passive Vibration Isolator
A hybrid active-passive vibration isolator made up of electromagnetic actuator and air spring in parallel can be used to effectively isolate the broadband and line spectrum vibration of mechanical equipment simultaneously. However, due to its reliability and safety problems caused by the impact, its application in ships is limited. In this paper, an impactresistant structure and an air gap self...
متن کاملDISTRIBUTED ACTIVE VIBRATION CONTROL WITH EMBEDDED SENSOR NETWORK TECHNIQUES By
The early promise of centralized active control technologies to improve the performance of large scale, complex systems has not been realized largely due to the inability of centralized control systems to “scale up”; that is, the inability to continue to perform well when the number of sensors and actuators becomes large. Now, recent advances in Micro-electro-mechanical systems (MEMS), micropro...
