数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此，数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分（PID）仿真由相应的离散传函实现，运用数字PID对被控对象实行准确控制。通过调节比例（P）、积分（I）、微分（D），使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)

PCA的步骤：
1 先将数据中心化；
2 求得的协方差矩阵；
3 求出协方差矩阵的特征值与特征向量；
4 将特征值与特征向量进行排序；
5 根据要降维的维数d’,求得要降维的投影方向；
6 求出降维后的数据；
(PCA steps: 1 of the first data center 2 covariance matrix obtained 3 obtained covariance matrix eigenvalues and eigenvectors 4 eigenvalues and eigenvectors will be sorted 5 according to the dimension of dimension reduction d ' , seek to reduce the dimension projection direction 6, the data obtained after the dimensionality reduction )

logintimeout
说明： 这个模型可以在MATLAB中，为数据库的进入，提供时间倒数，以防止过多地试密码，从而提高系统的保密性( TIMEOUT = LOGINTIMEOUT(FIRSTARG,SECONDARG) returns the current
value of time allowed for a connection to a database to be
successful. FIRSTARG, an optional argument, is a string that
specifies the JDBC driver to be used establishing the database
connection. SECONDARG, an optional argument, is an integer that
specifies the length of time the driver will attempt to make a
connection to a database. If FIRSTARG is not specified then the
default JDBC/ODBC bridge is used to establish the connection to
the database. If function is used without arguments then the
current time out value is returned. )
