Gravity compensation and optimal control of actuated multibody system dynamics
IET Control Theory & Applications, 2022 This work investigates the gravity compensation topic, from a control perspective. The gravity could be levelled by a compensating mechanical system or in the control law, such as proportional derivative (PD) plus gravity, sliding mode control, or ...

Passive Limitations for a Magnetic Gravity Compensator
Journal of System Design and Dynamics, 2009 The development of sophisticated advanced vibration isolation is important because even the minutest vibrations have disastrous effects on the performance of static and moving parts in high-precision machines. This paper concerns with the isolation of these vibrations for a large static body in an advanced micro-lithographic system, where a passive ...

Levitated Liquid Dynamics in Reduced Gravity and Gravity-Compensating Magnetic Fields [PDF]
JOM, 2012 Dynamic models are used to investigate the behavior of liquid droplets suspended in alternating current and direct current magnetic fields in microgravity and in various configurations providing conditions similar to microgravity. The realistic magnetic fields of solenoidal coils are used for the modeling experiments with electrically conducting ...
