Simulink: implementing a custom transfer function

Question

Let's say I implement this m-file:

Fq=tf(0.5^2,[1 2*0.7*0.5 0.5^2]);
G=tf(0.006*[200 1],[80 1 0]);
Q=Fq/G;

open Inner_Loop.mdl

Inside Inner_loop.mdl, if I want to implement/model a transfer function block using G, how can it be achieved easily? In other words, how can I retrieve the numerator and denominator of a tf easily?

Thanks in advance.

Answer 1

这是通过调用tfdata（）函数完成的，对于num这样的分子数据，需要在Simulink模型的传递函数块的数据字段中指定num {1}。
