A Novel Micro-G Emulation System Using Active Magnetic Compensator for Complex Space Operations

Abstract

Abstract-To perform the ground simulation experiments of the complex space operations, this work proposes a new active magnetic suspension compensator. The large-gap magnetic suspension compensator (LGMSC) is a conceptual design for a ground-based experiment which could be used to investigate the technology issues associated with accurate suspended element control at large gaps. This compensator can be used as the out-of-plane electromagnetic actuator for the 3-DOF fine stage in certain high precision positioning applications. Based on the equivalent current method, we explain the basics of the magnetic suspension compensator and analyze its advantages. A gravity compensator has been realized in a test setup that shows the feasibility of the chosen modeling technique and of magnetic gravity compensation.

Attitude stabilization and test validation of underactuated post-capture combination with multiple disturbances

“…[A detailed introduction of these methods and the global facilities may be seen in Yuan et al (2015) and Zhu et al (2016)]. To satisfy the flexibility, accuracy, complex operation and controllability, studies of test design and system development arose (Klimov and Poduraev, 2015; Viswanathan et al, 2013; Wen et al, 2016). In our laboratory, a novel facility has been established.…”
