As artificial satellites are large-sized and operated for a long period, the fuel on board for the reaction control system increases. Therefore, a conventional gas-pressure type fuel supply system will reach the limit from the standpoints of the weight and the capacity in no distant future. This research proposes a "linear motor pump system" as one of the countermeasures and studies for the pratical usage, in which we try to make the light fuel pump system with high efficiency by using the pump system driven by the linear motor for supplying the fuel to the engine. From 1991 to 1992, we have designed and produced a linear pulse motor (LPM) as a trial and pursued the research project for the purpose of measuring the basic characteristics, deriving and appraising the performance equation, establishing the optimum design method of the LPM in which the system weight is selected for the objective function and deciding the optimum control method.Principal results obtained by this work are as … More follows; 1. We produced a 4 pole, 25V, 150W LPM and power MOSFET inverter system and made certain that not only the motor functioned as designed but also the experimental standstill thrust characteristics agreed well with the theoretical results by use of our performance equations. 2. We composed a spring-mass system for the LPM mover, analyzed the motion and showed the relation between the rated thrust of the LPM, the stroke and the resonance frequency. We also developed the control algorithm and confirmed that the motor operated resonantly with little thrust according to the theory. 3. For studying the control strategy, we installed a new test equipment consisted of a LPM, a driver, strain gauges, a linear encoder, and measuring devices in 1992. In future, we will decide the best combinations of the spring constant, the rated thrust, the stroke and the resonance frequency in the spring-mas resonance system, and investigate the optimum control algorithm theoretically and experimentally.

随着人造卫星的大型化和长时间运行，反应控制系统所需的机载燃料越来越多。因此，传统的气压式燃料供应系统从重量和容量的角度来看，将在不远的将来达到极限。本研究提出了“直线电机泵系统”作为实际应用的对策和研究之一，试图利用直线电机驱动的泵系统来为发动机提供燃料，从而使轻型燃油泵系统具有更高的效率。从1991年到1992年，我们设计并试制了一台直线脉冲电机，进行了测量基本特性、推导和评价性能方程、建立以系统权重为目标函数的直线脉冲电机优化设计方法和确定最优控制方法的研究项目。本工作取得的主要结果如下：…1.研制了一台四极、25V、150W LPM功率MOSFET逆变系统，利用我们的性能方程，验证了该系统不仅电机功能正常，而且静推特性实验结果与理论结果吻合良好。2.建立了LPM电机的弹簧-质量系统，对其进行了运动分析，给出了电机额定推力、行程和共振频率之间的关系。并开发了相应的控制算法，从理论上验证了电机在小推力的情况下运行是谐振的。3.为了研究控制策略，我们于1992年安装了一套新的测试设备，包括LPM、驱动器、应变计、线性编码器和测量装置。今后，我们将确定弹簧-质量共振系统的弹簧常数、额定推力、行程和共振频率的最佳组合，并从理论和实验上研究最优控制算法。较少
