Consider a unity feedback system with ) 6 )( 4 )( 2 )( 2 2 ( ) 3 )( 1 ( ) ( 2 + + + + + + + = s s s s s s s K s G Use MATLAB to answer the following questions. (a) Plot the root locus. (b) Find the ω jaxis crossing and the gain , K , at the crossing. (c) Find the breakin and breakaway points. (d) Find the gain K to yield a damping ratio of 0.3 for the closedloop dominant poles. What is the expected overshoot? (e) Plot the closedloop step response and determine the overshoot. Hand in a plot of the root locus from MATLAB and mark on it the answers to parts (b) to (d)....
