Design of a magnetic gravity compensation system

Precision Engineering, 2006
An extremely accurate positioning over relatively long ranges is accomplished by absorbing or suppressing vibrations. Highly accurate frames or stages should be supported against gravity. In addition, the external disturbance forces acting on these stages need to be cancelled in a feedback control loop.

Gravity Disturbance Compensation for Inertial Navigation System

IEEE Transactions on Instrumentation and Measurement, 2019
This paper investigates the gravity disturbance compensation for inertial navigation system based on high-resolution global gravity field models. The high-precision gravity is calculated using the European Improved Gravity model of the Earth by New techniques (EIGEN)-6C4, which is a representative of the high-resolution models.

Electromagnetic Actuators for Gravity Compensation and Vibration Isolation

Sensor Letters, 2009
In contrast with the vibration isolation regime, which requires active elements, the gravity compensation can be provided in a passive manner, i.e., without the need for power consumption. This paper presents two types of electromagnetic actuators whose design focuses on the passive gravity compensation and, furthermore, incorporate active elements ...

Prismatic Gravity Compensator for Variable Payloads

IEEE Robotics and Automation Letters, 2022
Gravity compensators are passive devices that can lower the energy consumption of lifting systems by reducing the force/torque required from human users or actuators. This paper presents a prismatic gravity compensator for cranes, gantry, and other lifting systems.

PD control with on-line gravity compensation for robots with elastic joints: Theory and experiments

Automatica, 2005
A proportional-derivative (PD) control with on-line gravity compensation is proposed for regulation tasks of robot manipulators with elastic joints. The work extends a previous PD control with constant gravity compensation at the desired configuration ...
