(a) (5 points) Linearize this dynamical system about the zero equilibrium point, and write the linearized dynamical system in state space form. (b) (5 points) Compute the transfer function Y(s)/U(s). (c) (5 points) Show that the linearized-system is controllable, despite being unstable. (d) (5 points) Use Ackermann's formula to place the closed loop system eigenvalues at -3 and -5.
