(c) For the matrix f computed above, is the closed-loop system ˙ x = ( A + b f ) x stable? 1 5. Consider the following LTI system ˙ x = Ax + Bu , y = Cx + Du , x ∈ R n , u ∈ R k , y ∈ R m (CLTI) and a state-feedback control u =-Kx + v , where v ∈ R k denotes a new input. (a) Compute the state-space model of the closed-loop and its transfer function from v to y . (b) Show that if the original system (CLTI) is controllable then the closed-loop system is also controllable. Hint: Use the eigenvector test. 2...
