This paper concerns a discrete competitive system subject to feedbackcontrols. By using Lyapunov function and some preliminary lemmas, the existenceand uniformly asymptotic stability of unique positive almost periodic solution ofthe system are investigated. Numerical simulations suggest the feasibility of ourtheoretical results
