- 龙格---库塔方法是求解微分方程比较常用的方法,在理解数学上是怎么一回事后,编制这个程是相当容易的,就是个迭代的过程.步长的选取也是很有讲究的,过小的步长反而会导致误差累积过大. 相关的理论请参考相关的数值算法的书籍,我这里只给出关键的函数及主程序段,其余相关的细节就不再一一罗列了.-Runge - Kutta method to solve the differential equation is more commonly used method, in understanding h

- 对具有随机噪声的二阶系统的模型辨识,进行标幺化以后系统的参考模型差分方程为: y(k)=a1*y(k-1)+a2*y(k-2)+b*u(k-1)+s(k) 式中,a1=0.3366,a2=0.6634,b=0.68,s(k)为随机噪声。由于神经网络的输出最大为1,所以,被辨识的系统应先标幺化,这里标幺化系数为5。采用正向建模(并联辨识)结构,神经网络选用3-9-9-1型,即输入层i,隐层j包括2级,输出层k的节点个数分别为3、9、9、1个;由于神经网络的最大输出为1,因此在辨识前应对原系统参考模
