利用多元回归分析解决问题，通过对三个变量的分析选取最好的模型，并得到预测值(Solve problems using multiple regression analysis, analysis by three variables chosen best model and get the predicted value)

主成分分析，计算权重，特征值，以及相应的主成分(principal component analysis)

It has m files. These m files will run in matlab. Different kinds of table can be drawn by these m files

要求使用继电自整定方法对其实施自适应PID控制。 1、选择采样时间0.1s，把对象离散化。 2、加继电（开关）控制，测量对象的Tc,Kc。 3、利用ZIEGLER-NICHOLS 公式表，确定PID参数。 4、实现闭环控制。 5、根据调节效果，修正PID参数。 (Require the use of relay tuning methods for its implementation of the adaptive PID control. 1, select the sampling time 0.1s, the discrete objects. 2, plus relay (switch) control, measurement object Tc, Kc. 3, using ZIEGLER-NICHOLS formula table, determine the PID parameters. 4, closed loop. 5, according to moderating effect, the amendment PID parameters.)
