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.)

新建压缩文件
(1)设计一个“简易计算器”,主要实现判断输入的表达式是否合法将中缀表达式转换成二叉表达式树。后序遍历求出表达式的值。能判断输入的表达式是否合法。
(2)用链式存储存储信息,求值时可以采用递归的思想,对表达式进行后序遍历。
(3)将操作结果保存到外部文件。((1) Design a "simple calculator" to judge whether the input expression is legitimate or not and convert infix expression into binary expression tree. The value of the expression is obtained by post-order traversal. Can judge whether the input expression is legitimate. (2) Store information in chain mode. When evaluating the value, we can use the idea of recursion to carry out post-order traversal of the expression. (3) To save the operation results to external files.)
