A new general sufficient condition for almost sure stability of jump linear systems. (English) Zbl 0870.93048
Almost sure asymptotic stability of the discrete-time linear stochastic system $$x_{k+1}= H(z_k)x_k$$ is considered, where $$(z_k)$$ is a finite state Markov chain, not necessarily ergodic. With the help of a Lyapunov function, a sufficient condition is derived, together with several variants. It is given in terms of the quotients “norms of the possible new states over norm of the old state”, the norms properly chosen. The condition is necessary and sufficient in the case of a one-dimensional system; and it is a necessary condition for second moment stability.
