This Paper considers the convergence of systems subjected to zero-ergodic-mean disturbance. We first consider the stability of averaged systems and give an example showing that exponential stability does not imply averaged stability. Next a sufficient condition is established for a class of averaged systems to be stable. Using this result, we obtain conditions guaranteeing convergence of systems subjected to zero-ergodic-mean disturbance.
Keywords: stability; averaged systems; convergence; disturbance.
