Design of a Nonlinear Stiffness Unit Cell Aided Magnetic Gravity Compensator

A novel nonlinear stiffness unit cell aided magnetic gravity compensator is proposed for the purpose of isolating low-frequency vibrations. A negative stiffness magnet setup is combined with a compliant unit cell with tailored nonlinear force-displacement characteristics. This combination offers a large range of motion featuring low stiffness, a...

Localization and Control of a Magnetic Levitation Positioning System

Magnetic levitation is a recent technology which nowadays is used in high-tech systems. It is developed due to the inherent benefits of these type of setups such as lack of wear, friction and problems due to mechanical phenomenon as play and backlash. Achieving higher accelerations and ultra-precise position control while reducing maintenance. ...
