[b,a] = ss2tf(A,B,C,D) converts a state-space representation of a system into an equivalent transfer function. ss2tf returns the Laplace-transform transfer function for continuous-time systems and the Z-transform transfer function for discrete-time systems. example [b,a] = ss2tf(A,B,C,...
>>>fromscipy.signalimportss2tf>>>ss2tf(A, B, C, D) (array([[1.,3.,3.]]), array([1.,2.,1.]))
iu是多输出时候的输出序号，[num1, den1]=ss2tf(A, B, C, D, 1) 表示一个输出，[num2, den2]=ss2tf(A, B, C, D, 2)就可以 表示二个输出，在matlab里面运行一下就清楚怎么回事了。
[num,den] = ss2tf(A,B,C,D,i) 其中,A、B、C和D分别表示状态空间模型的四个参数,i为输入信号的通道数。函数的返回值为传递函数的分子系数num和分母系数den。 三、SS2TF函数的使用方法 1. 确定系统的状态空间模型 在使用SS2TF函数之前,首先需要确定系统的状态空间模型,即A、B、C和D四个参数的值。通常情况...
