Sontag, Eduardo D.
A universal' construction of Artstein's theorem on nonlinear stabilization.
(English)
[J] Syst. Control Lett. 13, No.2, 117-123 (1989). ISSN 0167-6911

Summary: This note presents an explicit proof of the theorem - due to {\it Z. {\it Artstein}} [Nonlinear Anal., Theory Methods Appl. 7, 1163-1173 (1983; Zbl 0525.93053)] - which states that the existence of a smooth control- Lyapunov function implies smooth stabilizability. Moreover, the result is extended to the real-analytic and rational cases as well. The proof uses a universal' formula given by an algebraic function of Lie derivatives; this formula originates in the solution of a simple Riccati equation.
