I remember loathing any assignment requiring root-locus plots. I never really got much out of them anyway (maybe it was just how it was presented). I'm pretty sure I learned more about the control system while making the root-locus plot than anything the plot actually told me when it was done. I've wondered why more teams haven't done LQR or lead-lag compensators. I seem to remember a good LQR was somewhat easy to implement if you knew the dynamics of your system pretty well, but I believe PID is probably more forgiving if you don't fully understand it. Is there any truth to that?
