Consider the system represented by the block diagram and its Root Locus Plot for a given value of parameter ‘a’.
Determine:
a) The value of ‘a’ for which the system becomes critically damped at the point
(-3 +j0) of the Root Locus Plot.
b) The value of
K at this point.
c) The intervals for the values of
K for the system to be overdamped and underdamped.
