Abstract: In this paper, the geometric stabilization problem of nonlinear stochastic discrete- time systems is studied. Firstly, the concept of geometric stochastic incremental QSR dissipativity for nonlinear stochastic discrete-time systems is introduced, and the expression of the concept of linear matrix inequality (LMI) is given. Secondly, based on the geometric stochastic incremental QSR dissipativity and the linear static output feedback controller, the sufficient and necessary conditions for the geometric mean square incremental stability in probability of the system are proposed. Finally, the validity of the results is demonstrated by numerical simulation.
