Hautus Lemma for controllability. The Hautus lemma for controllability says that given a square matrix [math]\displaystyle{ \mathbf{A}\in M_n(\Re) }[/math] and a [math]\displaystyle{ \mathbf{B}\in M_{n\times m}(\Re) }[/math] the following are equivalent: The Hautus Lemma, due to Popov [18] and Hautus [9], is a powerful and well known test for observability of ﬁnite-dimensional systems. It states that the system (1.1) with A ∈ C n× and C ∈ Cp×n is observable if and only if rank sI −A C = n for all s ∈ C. (1.2) Russell and Weiss [20] proposed the following generalization of the Hautus test to the In control theory and in particular when studying the properties of a linear time-invariant system in state space form, the Hautus lemma, named after Malo Hautus, can prove to be a powerful tool.

2021-2-6 · Just for clarification: Using the hautus lemma on all eigenvalues with a non-negative real part yields that for system 2 eigenvalue $0$ is not observable and for system 4, $1+i$ is not controllable. So 2 and 4 are not BIBO? You previously mentioned :"if all the unstable modes/eigenvalues of a system are not controllable then those states can Lemma 28 from (which is an operatorial version of the Schur complement Lemma) ensures that iff (if and only if) .
