Formally, it says Lemma 1 (Heymann's Lemma) : If (A, B) is controllable, then for any b = Bv = 0 there exists K (that depends on b) such that (A + BK, b) is controllable.

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. Wikipedia

Hautus lemma Via Hautus Lemma – practical: rank[λI − A B] = n for all λ ∈ eig(A).

In [Hau94], Hautus provided a An extension of the positive real lemma to descriptor systems. Strictly positive real lemma and absolute stability for discrete-.

( A , C ) {\displaystyle (\mathbf {A} ,\mathbf {C} )} is detectable. 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.

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.

Heymann's lemma is proved by a simple induction argument • The problem of pole assignment by state feedback in the system (k = 0,1,•••) where A is an n x n-matrixand B an n x m-matrix, has been considered by many authors. The case m = has been dealt with by Rissanen [3J in 1960. first - class functions if it treats functions as first - class citizens.

An equivalent statement is the Hautus lemma: it characterizes observability by the condition ∀λ ∈ C: rank[λI −A,C] = n that clearly is equivalent to the condition (1.2) kCxk2 +k(λI −A)xk2 ≥ κkxk2.

Lemma 1.2 (Hautus). Given an n × n matrix A and an n × m matrix B, the linear system x• = Ax + Bu is locally exponentiallystabilizable if and only if for all λ ∈ Λ+(A) it holds that rank λI −A B = n.
