P. Bougerol, ALMOST SURE STABILIZABILITY AND RICCATIS EQUATION OF LINEAR-SYSTEMS WITH RANDOM PARAMETERS, SIAM journal on control and optimization, 33(3), 1995, pp. 702-717
Linear systems with stationary time-varying parameters are considered.
The notions of almost sure stabilizability and almost sure detectabil
ity are explored. Under these properties the asymptotic behavior of th
e associated Riccati equation is described. In particular the stabilit
y of the Kalman filter and the convergence of linear observers are pro
ved.
