In this paper, a new type of stability for nonlinear systems of differential equations called practical ψγ-exponential asymptotic stability, is presented. Some sufficient conditions for practical ψγ-exponential asymptotic stability are provided by using Lyapunov theory. These results generalize fundamental well known results for practical exponential asymptotic and ψ-exponential asymptotic stability for nonlinear time-varying systems. In addition, these results are using to investigate the practical ψγ-exponential asymptotic stability problem of nonlinear perturbed system and cascade systems. The last part is devoted to the study the problem of practical ψγ-exponential asymptotic stabilization for some classes of nonlinear systems with delayed perturbation. [ABSTRACT FROM AUTHOR]
