分析了永磁同步电机矢量控制的发展概况，然后从机电能量转换的角度出发，解释三相永磁同步电机的机电能量转换原理，推导拉格朗日运动方程。此外，列写出永磁同步电机在三相静止坐标系和dq坐标系下的数学模型。基于Simulink建立了转速电流双闭环矢量控制系统的仿真模型，通过对仿真结果分析，验证了永磁同步电机矢量控制系统性能的优越性(The development of vector control of permanent magnet synchronous motor is analyzed. Then, from the perspective of electromechanical energy conversion, the principle of electromechanical energy conversion of three-phase permanent magnet synchronous motor is explained, and the Lagrangian motion equation is derived. In addition, the mathematical model of the permanent magnet synchronous motor in the three-phase stationary coordinate system and the dq coordinate system is written. Based on Simulink, the simulation model of the speed and current double closed-loop vector control system is established. The simulation results are analyzed to verify the superiority of the performance of the permanent magnet synchronous motor vector control system.)

内部排序算法比较 一、需求分析 1． 实验要对以下6种常用的内部排序算法进行实测比较：起泡，直接插入，简单选择，快速，希尔，堆排序。 2． 待排序表的表长不小于100，其中的数据要用伪随机数产生（RAND（）），至少要用5组不现的输入数据作比较，比较的指标为有关键字参加的比较次数和关键字参加的比较次数和关键字的移动次数。 3． 最后要对结果作出简单分析，包括对各组数据得出结果波动大小的解释。 -internal sorting algorithm 1, a demand analysis. Experiment on the following six kinds of internal sorting algorithm measured comparison : foaming, direct insertion, simple choice, rapid, Hill, Heap Sort. 2. Sorting tables to the long table is not less than 100, which use the data generated pseudo-random number (RAND ()), be at least five sets of input data are provided for comparison. comparable indicators for the keyword in the number of keywords and the number of participants and the number of mobile keyword. 3. Finally, the results of a simple analysis, including data on the outcome of fluctuations in the size of explanation.
