对简单闭环系统的PID控制参数进行优化，得到最佳的控制效果。使用时将该文件夹设为matlab默认文件夹，用simulink打开.mdl文件，在命令行窗口输入.txt文档中命令，可以得到优化后的P、I和D参数。(The PID control parameters of the simple closed-loop system are optimized to obtain the best control effect. With using these codes, the folder must be set as the default folder of matlab, then open the. MDL file, and input the commands of . TXT document in the command line window. The optimized P, I and D parameters will be obtained.)

基于状态方程的两自由度振动微分方程simulink程序(Simlink Program for Two-Degree-of-Freedom Vibration Differential Equation Based on State Equation)

利用朴实贝叶斯方法求解有关肺炎的问题。肺炎对应有四个特征：发烧、疼痛、咳嗽和血细胞异常，当确定了患肺炎与否时，四个特征条件独立。假设患肺炎与否和四个特征都可表示为Ture和False。 根据pneumonia.tex文件中的数据（500行，每行前4个数对应4个特征变量，第5个数对应患肺炎是否为真，以0表示False，1表示Ture），编写Matlab 程序 maininference.m，从example.txt中读取病人的症状信息（0表示False，1表示True，-1表示not given），并计算对应的患肺炎的可能性。所给的信息按发烧、疼痛、咳嗽、血细胞异常的顺序排列。将计算结果保存在answer.txt中。(Simple Bayesian method to solve the question of pneumonia. Pneumonia corresponding four characteristics: fever, pain, cough and blood cell abnormalities, determine the risk of pneumonia or not, the four characteristics of conditional independence. Assumptions suffering from pneumonia or not and four features can be represented as Ture and False. According to the data pneumonia.tex file (500 lines, each line of the first four numbers corresponding to the four characteristic variables, number 5 corresponds to the risk of pneumonia is true, 0 represents False, said Ture), to write Matlab program maininference. m from example.txt read the information of the patient' s symptoms (0 = False, said True, the-1 indicates not given), and to calculate corresponding to the likelihood of suffering from pneumonia. The information given by the order of fever, pain, cough, blood cell abnormalities. The calculated results is be saved in answer.txt.)
