基于BP网络预测的matlab程序，可以用于BP网络预测，matlab编译通过(BP network based on the forecast matlab procedures, can be used in BP network prediction, matlab compiler through)

数字控制系统仿真与综合应用：设控制对象为 W1=10/s(1+0.1s)(1+0.05s),采样周期T=0.2s。 （1）采用零阶保持器，将W1(s)转换成W1(z),串接一个计算机调节模型D(z)组成一个典型的数字反馈系统。分别用仿真方法得到系统在单位阶跃输入作用下的响应和系统在单位速度输入时的输出响应。 (Digital control system simulation and comprehensive application: set control object for W1 = 10/s (1+ 0.1 s) (1+ 0.05 s), the sampling period T = 0.2 s. (1) the zero order keep device, will W1 (s) convert W1 (z), the combination of a computer adjusting model D (z) composed of a typical digital feedback system. The simulation method were used to get in the unit step input system under the action of response and system in the unit of output response speed input. )
