基于stm32开发板的简单应用，LED闪烁，跑马灯及蜂鸣器的应用。(Based on the simple application of STM32 development board, the application of LED scintillation, horse-running lamp and buzzer.)

基于模型预测的永磁同步电机直接转矩控制，通过建立其预测模型，并且评估每个电压矢量作用所产生的结果，选择最优的电压矢量并得到其PWM信号施加到变压器上以此来控制PMSM的转矩。该文件包含仿真文件，但是不包含模型预测控制的程序，程序获取方式在文件中(Direct torque control of permanent magnet synchronous motor based on model predictive control is established. By establishing its prediction model and evaluating the result of each voltage vector action, we select the optimal voltage vector and get the PWM signal to be applied to the transformer to control the torque of PMSM.)

说明：  以悬臂梁为例，用有限元法编程生成质量矩阵和刚度矩阵（采用平面梁单元，单元数在10到30之间）。 使用matlab的用于广义特征值问题分析的函数（eig(A,B,'chol')，该命令使用乔莱斯基分解的方法，计算对称矩阵A和对称正定矩阵B的广义特征值问题。A对应刚度矩阵，B对应质量矩阵）计算梁的前三阶固有频率和振型，计算得到梁的前三阶固有频率和振型，并画出振型图。(Taking cantilever beam as an example, the mass matrix and stiffness matrix are programmed by finite element method (using planar beam elements, with units ranging from 10 to 30). Using Matlab's function (eig (A, B,'chol') for the generalized eigenvalue problem analysis, the command uses the Jo Lessky decomposition method to calculate the generalized eigenvalue problem of the symmetric matrix A and the symmetric positive definite matrix B. A corresponds to the stiffness matrix and B corresponding to the mass matrix. The first three natural frequencies and modes of the beam are calculated, and the first three natural frequencies and modes of the beams are calculated, and the vibration pattern is drawn.)
