项目摘要

With increasing consumption of fuel in an artificial satellite reaction control system, the high pressure tank of conventional pressurized-gas feed type fuel supply system has increased in size and weight. In the previous work, we proposed a new type fuel pump system with linear motor propulsion, inwhich two pumps were equipped on both sides of a linear motor and resonant system with springs was organized to decrease the rated thrust. The aim of this research is to develop the light weight and small size linear motor most suitable for the quick reciprocating motion use and investigate the optimum control strategy.Principal results obtined by this work are as follows ;1. For studying the motion control, we install a new experimental apparatus consisted of a linear pulse motor (LPM), a driver and measurement devices such as position sensor and thrust sensor. It is confirmed experimentally that the LPM reciprocates as instructed. After adding the regenerative braking function to the driver, we will decide the best combinations of the spring constant, the rated thrust, the stroke and the resonance frequency in the spring-mass resonance system and investigate the optimum control algorithm experimentally.2. We develop a method of optimizing the design parameters of the linear motor using nonlinear programming technique and we, moreover, apply the multi-objective programming technique to the optimization program. We design and produce a small-sized single sided linear induction motor by use of the optimization program. Now, we have been improving the inverter system for studying the vector control.3. We research the design method and analytical method for linear direct current motors. Now, we are making the optimization program.

随着人造卫星反应控制系统中燃料消耗的增加，传统的加压气体供给式燃料供应系统的高压罐的尺寸和重量也随之增加。在前期工作中，我们提出了一种采用直线电机推进的新型燃油泵系统，在直线电机两侧配备两个泵，并组织弹簧谐振系统来降低额定推力。本研究的目的是开发最适合快速往复运动使用的轻量、小尺寸直线电机，并研究最佳控制策略。本工作取得的主要结果如下： 1．为了研究运动控制，我们安装了一个新的实验装置，该装置由线性脉冲电机（LPM）、驱动器以及位置传感器和推力传感器等测量装置组成。实验证实LPM按指令往复运动。在驱动器上增加再生制动功能后，我们将确定弹簧-质量共振系统中弹簧常数、额定推力、行程和共振频率的最佳组合，并通过实验研究最优控制算法。2．我们开发了一种使用非线性规划技术优化直线电机设计参数的方法，并将多目标规划技术应用于优化程序。我们利用优化程序设计并生产了小型单面直线感应电机。目前，我们正在对逆变系统进行改进，研究矢量控制。 3．研究直线直流电机的设计方法和分析方法。现在，我们正在制定优化方案。
