ABSTRACT This paper focuses on the secure control design of networked systems (NCSs) under replay attacks. Mitigating attacks is a challenging task since statistical similarity between replayed signals and real observations makes them difficult to distinguish. Given persistence potential attackers probability individual attack failures, novel switching‐based model introduced. By employing this model, NCSs vulnerable can be transformed into class switching‐like systems. Within framework...

The inherent complexities associated dynamics parametric uncertainties make it difficult to mitigate switching bumps caused by abrupt jumps in input signal. Existing approaches, such as tuning controller or limiting gains, have proven ineffective resolving this challenge. To overcome this, an auxiliary system is constructed...
