Also, is your expression for \$X\$ after "subject to" the DARE, because the expression you used doesn't seem to be completely correct. \$\endgroup\$ – Kwin van der Veen Jun 29 '20 at 23:53 2017-11-17 · List of Examples and Statements xxxiii 8.7 Theorem: Local contraction for Newton-type methods .

(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. 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。 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.

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. There is a similar result to the Hautus lemma, which applies to the linearization of a system like that given in (1). That 1.4 Lemma: Hautus lemma for observability . .

The pair (A;B) is stabilizable if and only if A 22 is Hurwitz. This is an test for stabilizability, but requires conversion to controllability form. A more direct test is the PBH test Theorem 3.
