Abstract
This note considers the long-run aver- age cost control problem for a class of discrete-time stochastic systems. The stochastic system is assumed to be linear with respect to the state but the controls possess a general structure, possibly a nonlinear one. The main contribution of this paper is to show that the existence of a minimal second moment system state implies the existence of an optimal stationary policy for the long-run average cost problem. A numerical example illustrates the derived result. © 2010 AACC.373377Syrmos, V., Abdallah, C., Dorato, P., Grigoriadis, K., Static output feedback- A survey (1997) Automatica, 33, pp. 125-137Vargas, A.N., Do Val, J.B.R., On the existence of stationary optimal policies for the average-cost control problem of linear systems with abstract state-feedback (2008) Proc. 47th IEEE Conf. on Decision and Control, pp. 3682-3687. , Cancun, MexicoA bounded cost condition for the existence of average optimal stationary policies of linear stochastic systems (2009) Proc.
