PMSM控制系统采用速度电流双闭环矢量控制调速系统，即控制系统中有速度调节器和电流调节器。(PMSM control system adopts speed and current double closed-loop vector control speed regulation system, that is, speed regulator and current regulator are included in the control system.)

说明：  采用ANSYS软件的APDL语言编写的两个命令流文件，用于计算含缺陷管道的失效概率，将参数稍作改动，可用于其它结构的可靠性分析(Two command stream files written in APDL language of ANSYS software are used to calculate the failure probability of defective pipeline. The parameters can be changed slightly and can be used for reliability analysis of other structures.)

使用CW方程，使用最小能量，采用脉冲推力，实现在一天内两航天器的交会对接。本质上就是一个交会轨道优化问题，由给定的条件优化选取设计变量，使目标函数得到最优值。(Using the CW equation, use the minimum energy, the use of pulse thrust, to achieve in a day two spacecraft rendezvous and docking. Is essentially an intersection orbit optimization problem, by the given conditions to optimize the selection of design variables, so that the objective function to get the optimal value.)
