11 Problem A6.12 OGATA 4edition (root locus)




Let us calculate the root-locus of a closed-loop system with feedback by Scilab, whose transfer function in open loop is:

\begin{displaymath}G(s)=\frac{K}{s\cdot (s+1)\cdot (s+2)}\end{displaymath}


Program in Scilab
s=%s;
num=1;
den=s*(s+1)*(s+2);
g=syslin('c',num/den);
clf;
evans(g);
v=[-4 4 -4 4]
mtlb_axis(v);
xgrid;
