Vibration Reduction System Using Magnetic Suspension Technology

Vibration Isolation System Using Zero-power Magnetic Suspension

A new vibration isolation system is proposed which uses zero-power magnetic suspension. Since a zero-power system behaves as if it has a negative stiffness, combining it with a normal spring can generate infinite stiffness against disturbances on the isolation table. It enables the system to have good performance both in reducing vibration transmitted from ground and in suppressing direct vibra...

Vibration Control of Mechanical Suspension System Using Active Force Control

This paper presents the practical implementation of an active force control (AFC) strategy to a laboratory scaled vibration isolator platform. The research was carried out to investigate the performance of vibration suppression capability of feedback controller using AFC. Two types of controller schemes were examined and compared involving the classic proportionalintegral-derivative (PID) contr...

Simulation and Control of Rotational Vibration of Sprayer Boom Using a Novel Suspension System

Sprayers are important tools in agriculture that usually moved on the field by tractor. Sprayers should distribute the constant rate of chemicals during various conditions encountered in the field. Unwanted vibrations of sprayer boom cause redaction of its life time and over doses and under doses of chemical sprayed on the field. Therefore, in this study a model of suspension system for rotatio...

Control Using Sliding Mode Of the Magnetic Suspension System

This paper presents a proposition of sliding mode position controller of the magnetic suspension ball system . The magnetic suspension system (MSS) is a mechatronic system already acknowledged and accepted by the field experts. The design of a controller keeping a steel ball suspended in the air. In the ideal situation, the magnetic force produced by current from an electromagnet will counterac...
