DOI: 10.2514/1.j062361
Abstract: Spacecraft electromagnetic docking has many potential advantages, such as no propellant consumption and plume contamination, while providing high-precision, continuous, reversible, synchronous, and noncontacting control capabilities. With these advantages, there are strong dynamic nonlinearity and coupling,… read more here.
