Electrodynamic tethers (EDTs) are an innovative approach to generate propulsion for boost and deorbit maneuver and electricity onboard spacecraft without consuming propellant. Over the past five decades, 12 out of 26 orbital and suborbital tether missions flew with EDTs. However, the system is prone to the long-term instability caused by the time-varying excitation of Lorentz force. Thus, a thorough understanding of the long-term dynamic stability of an EDT system is essential for its useful application in space.

电动力系绳（EDTs）是一种不消耗推进剂而产生推进力和离轨机动以及航天器上电力的创新方法。在过去的50年里，26次轨道和亚轨道系绳任务中有12次使用了edt。但由于洛伦兹力的时变激励，系统容易出现长期不稳定。因此，全面了解EDT系统的长期动态稳定性对于其在空间中的有效应用至关重要。
