# This condition, called $({\bf E})$, is related to the Hautus Lemma from finite dimensional systems theory. It is an estimate in terms of the operators A and C alone (in particular, it makes no reference to the semigroup). This paper shows that $({\bf E})$ implies approximate observability and, if A is bounded, it implies exact observability.

The result deals with the  using these so-called resolvent conditions, also known as Hautus tests. It proves new eitA/t>0 is a unitary group, the resolvent condition (10) and Lemma 2.7. Using the Hautus lemma , we can obtained a number a conditions that Lemma 3.1 (Hautus observability) For a linear system defined by the matrices A ∈.

This saves me a ton of time. 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.

### 1.6 The Popov-Belevitch-Hautus Test Theorem: The pair (A,C) is observable if and only if there exists no x 6= 0 such that Ax = λx, Cx = 0. (1) Proof: Suﬃciency: Assume there exists x 6= 0 such that (1) holds. Then CAx = λCx = 0, CA2x = λCAx = 0, CAn−1x = λCAn−2x = 0 so that O(A,C)x = 0, which implies that the pair (A,C) is not observable.
