Homework Statement
I'm trying to analyze the root locus of this transfer function in Matlab to control a DC motor:
mysys=tf([0.022],[0.00000000007 0.0000000626 0.000493])
The Attempt at a Solution
Using:
%[Kp,P]=rlocfind(mysys)
%rltool(mysys)
rlocus(mysys)
I get a root locus that looks somewhat odd and I'm not really sure how to interpret it. It doesn't appear to be stable at all gains. Although, it does look a bit better when I add a zero in rltool to the right of that gap and then it seems stable at all gains.
Help? I'm lost.
