错误提示与代码不对应吧,我运行了下程序没有错误.
Gzp1,Gzp2,Gs,Gp的结果分别如下
Zero/pole/gain:
(s+1)
----------------
s (s^2 + s + 1)
Zero/pole/gain:
2 (s+1.5)
---------
(s+1)^2
Transfer function:
2 s^2 + 5 s + 3
-------------------------------
s^5 + 3 s^4 + 4 s^3 + 3 s^2 + s
Transfer function:
2 s^4 + 6 s^3 + 8 s^2 + 6 s + 1
-------------------------------
s^5 + 3 s^4 + 4 s^3 + 3 s^2 + s
