The nonlinear two-time-scale system is decoupled into fast and slow subsystems by using the singular perturbation theory, and the aperiodic event-triggered intermittent control method is used to study the input-to-state stability.Firstly, the event-triggered conditions are designed for the fast and slow subsystems and the corresponding stability conditions are given, and then the event-triggered intermittent controller is designed according to these conditions. The Lyapunov function method is used to prove the input-to-state stability of the system under the aperiodic intermittent controller. Finally, the correctness of the theoretical results is verified by numerical simulation experiments.
