Resumo
This paper investigates the impact of Denial-of-Service (DoS) attacks on sampled-data control systems with non-uniform sampling and extends the analysis to cloud-based control architectures subject to random delays and packet losses. A Lyapunov-based framework is developed to ensure exponential stability of linear time-invariant (LTI) systems under DoS conditions, with sufficient conditions derived via linear matrix inequalities (LMIs). Numerical simulations illustrate the performance of both local and cloud-based controllers, revealing that while both architectures achieve stability, the cloud-based implementation suffers from degraded transient performance due to communication uncertainties. The results highlight the trade-offs between resilience and performance in modern networked control systems.
