| Abstract: | A sufficient condition for stability of time-varying discrete systems is proposed in this paper. Then stability of linear and nonlinear time-varying discrete large scale systems is studied respectively when their isolated subsystems satisfy the above condition. The aggregated model of time-varying discrete large scale systems in stability is obtained by the method of vector Lyapunov function and comparison principle of time-varying discrete systems. The conditions for stability of the large scale systems are directly obtained by the aggregated systems. |
