WebbThe controllability matrix C =[B AB]= # 1 −1 −3 3 0 0 1 −1 $ has full rank (2), meaning that the system is controllable. The observability matrix O = 5 C CA 6 = 5 1 1 −1 −1 −2 −2 2 2 6 has rank 1, meaning that the system is not observable. b. The silent states are given by the null space of the observability matrix, i.e., by Ox0 =0. WebbSince the rank of the controllability matrix Co is equal to the number of states, the system sys is controllable. Alternatively, you can also use just the A and B matrices to find the controllability matrix. Co = ctrb (sys.A,sys.B); rank (Co) ans = 2 Input Arguments collapse all A — State matrix Nx-by-Nx matrix
