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.

Popov-Belevitch-Hautus (PBH) test, which is a linear alge- braic result (also referred to as Hautus Lemma) in control theory [19], this is equivalent to that

Now we want to ﬁnd the transformation matrix P such that P−1A = A 1 A 2 0 λ P−1, P−1b = b 1 0 where λ = 0 is the uncontrollable A simple proof of Heymann's lemma. Hautus, M.L.J. / A simple proof of Heymann's lemma. Eindhoven : Technische Hogeschool Eindhoven, 1976. 3 p. 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).

To find such a decomposition, we note that a change of basis mapping A into TAT−1 via the nonsingular $\begingroup$ Thanks. 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.

Hautus引理（Hautus lemma）是在控制理论以及狀態空間下分析线性时不变系统時，相當好用的工具，得名自Malo Hautus ，最早出現在1968年的《Classical Control Theory》及1973年的《Hyperstability of Control Systems》中，現今在許多的控制教科書上可以看到此引理。

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.

The Hautus lemma for detectability says that given a square matrix. A ∈ M n ( ℜ ) {\displaystyle \mathbf {A} \in M_ {n} (\Re )} and a. C ∈ M m × n ( ℜ ) {\displaystyle \mathbf {C} \in M_ {m\times n} (\Re )} the following are equivalent: The pair. ( A , C ) {\displaystyle (\mathbf {A} ,\mathbf {C} )} is detectable.
