Thispaper isconcerned withcharacterization ofeasily-controllable plants inpractice, andattempts toobtain a quantitative result that relates thephase property oftheplant andtheachievable control performance inXOOloopshaping design. Inparticular, theconnection between thegain atthecritical phase delay of180(degree) andtheachievable control performance t)opt < 4+2 2isclarified.
