Scilab Function

kpure - continuous SISO system limit feedback gain

Calling Sequence

g=kpure(sys)

Parameters

Description

kpure(sys) computes the gains g such that the system sys feedback by g ( sys/.g ) has poles on imaginary axis.

Examples


s=poly(0,'s');
h=syslin('c',(s-1)/(1+5*s+s^2+s^3))
xbasc();evans(h)
g=kpure(h)
hf=h/.g(1)
