The permanence and global attractivity of Lotka–Volterra competition system with feedback controls

In this paper, we consider a nonautonomous Lotka–Volterra system with feedback controls. Some averaged conditions for the permanence and global attractivity of this system are obtained. Our results generalized those obtained by Zhao et al. (Nonlinear Anal.: Real World Appl. 5 (2004) 265–276).
