How to minimize the system when I have same pole and
zero ?
In the following example, I have the same term "(s+1)"
in the num and den of system,x. How can I remove them
so that x=1/(s+1) ?
octave:54> x=tf( [1 1], [ 1 2 1]);
octave:55> sysout(x,"zp");
Input(s)
1: u_1
Output(s):
1: y_1
zero-pole form:
1 (s + 1)
-----------------
(s + 1) (s + 1)
