Consider the system
x_dot = [[0, 1, 0], [0, 0, 1], [2, 1, -2]]x + [[3a, 3b], [3, 3], [1, -1]]u
y = [[alpha, 1, 1], [2, beta, 1]]x
a. Find the eigenvalues and eigenvectors of the system.
b. Find the state transition matrix.
c. Determine when the system is controllable.
d. Determine when the system is observable.
