The rank of controllability matrix
Webband only if the rank of the system matrix is full. Observability and controllability tests will be connected to the rank rests of certain matrices [6].

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.
