Vibration Isolation of Precision Objects
The need for vibration isolation of precision and vibrationsensitive objects is increasing continuously. Vibration isolation systems must comply with contradictory specifications, such as requiring reduced stiffness of isolators for better isolation, but higher stiffness for better performance of the object. Recently, expensive active isolation systems have been used to resolve these contradict...

متن کاملDecentralized control for multichannel active vibration isolation
This paper describes a theoretical and experimental investigation into an active four-mount vibration isolation system, in which electromagnetic actuators are installed in parallel with each of the four passive mounts placed between a three-dimensional piece of equipment and a vibrating base structure. Decentralized velocity feedback control is applied, where each actuator is operated independe...
متن کاملActive Vibration Isolation of Multi-Degree-of-Freedom Systems
One of the principal objectives of vibration isolation technology is to isolate sensitive equipment from a vibrating structure or to isolate the structure from an uncertain exogenous disturbance source. In this paper, a dynamic observer-based active isolator is proposed that guarantees closed-loop asymptotic stability and disturbance decoupling between the vibrating structure and isolated struc...
متن کاملApplication of Compliant Mechanisms to Active Vibration Isolation Systems
Compliant mechanisms have been designed for various types of applications to transmit desired forces and motions. In this paper, we explore an application of compliant mechanisms for active vibration isolation systems. For this type of application, an actuator and a compliant mechanism are used to cancel undesired disturbance, resulting in attenuated output amplitude. An actuator provides exter...
