: A sequential network has one input (X) and two outputs (Z1 and Z2). An
output Z1 Z2 = 10 occurs every time the input sequence 1011 is
completed. An output Z1 Z2 = 01 occurs every time the input sequence
0101 is completed. Otherwise Z1 Z2 = 0

1. Suppose you want to build a lead compensator so that -3 ± 5j are dominant poles.
You observed that the angle deficiency at the desired dominant pole is 50°. Compute a
's+b'
and b of the lead compensator (s+ 2) so that the error constant Ky is maximized. In other
words, design the lead compensator in a way so that the steady-state error for ramp input
is minimum
