Consider the single-input, single-output system is described by

y(t) = Cx(t)
where

(a) Determine the value of K resulting in a zero steady-state tracking error when u(t) is a unit step input for t ‰¥ 0 . The tracking error is defined here as e(t) = tt(t) - y(t).
(b) Plot the response to a unit step input and verify that the tracking error is zero for the gain K determined in part (a).

k(1) = Ax(1) + Bu(1) 8 A= . C= [1 0]
