System modeled by Eigenvectors

Consider the system modeled by:

x' = Ax + Bu , y = Cx + Du

-5 1 -1
A = , B = , C=[1 0] , D=0
1 -5 1

a) Determine the transition matrix eAt using the eigenvalues and eigenvectors method

b) Find x(t) and y(t) if the input is a unit step function when x(0)=[3 -1]T

3
c) Determine the controller u(t) if x(0) = and
-1

2e-21+ e-12
x(3) =
