In this paper propulsion systems for space station control is discussed.It is concluded that propellant consumption will be a major cost factor. Electric propulsion system offers specific impulse at least an order of magnitude higher than those of chemical thrusters, so propellant masses can be reduced by the same factor. Electic propujsion systems will be used for high impulse tasks such as drag compensation and orbit transfer.

A naval ship electric propulsion unit is a complex ship-machine-electricity system.The current method of studying its dynamic characteristics by building the model based on the theoretical analysis often meets trouble in practice,for the analysis is complicated,and the model obtained cannot be put into practice easily.This paper makes a tentative study on the introduction of system identification method into the analysis of the dynamic characteristics of the naval ships' electric propulsion system. The structure and parameters of the model are through a practical test of ship model and an identifica- tion computation.In order to overcome the influence of correlated noise,Recursive Extended Least Squares(RELS)method is used in parameter estimation,and the model is tested in its fitting degree and convergence.The result indicates that the dynamic model obtained through the above-mentioned method is applicable.

舰船电力推进是一个复杂的船—机—电系统。对其动态特性的研究,利用现有的基于理论分析建立机理模型的方法,就会遇到分析过程繁杂、模型适用性差的实际困难。本文则利用系统辨识方法建立舰船电力推进系统的动态模型,通过一个具体的船模实验及辨识计算,确定模型的结构和参数。为了克服相关噪声的影响,参数估计中采用了增广矩阵法。并对模型从拟合程度和收敛性两方面进行了检验,结果表明,上述方法所得到的动态模型是适用的。
