Consider the following controlled continuous LTI system
1. Initially, set u(t) = 0. How many equilibrium points does the system have?
2. Is the system controllable? Define which modes are controllable and which modes are uncontrollable.
3. Is the system observable? Define which modes are observable and which modes are not observable
4. Design, if possible, a feedback controller in the form u(x1, x2) = -k^T x = -k1x1 - k2x2 such that the output of the system behaves as y(t) = y0e^-t for any possible y0 ∈ ℝ
