چکیده :

An objective of this study is to design a robust model predictive control (RMPC) strategy for Cyber-Physical systems (CPSs) that are affected by bound disturbances and deception attacks. Based on the assumption that deception attacks have norm-bounded structures, a model of attack has been developed using Bernoulli-distributed white sequences. In addition, we propose a new observer-based augmented closed-loop controller that performs two main functions. The first step is to estimate the state of all system components at any given time. As a second step, it is necessary to ensure that some unprotected communication channels are prevented from having an adverse deception cyber-attack effect on the system's response. An output-feedback controller for detecting cyber-attacks is investigated based on the estimated states. As a result, all CPS states under deception cyber-attacks appear to be convergent under the proposed approach. Linear matrix inequalities are used to formulate the requirement. To demonstrate the applicability of the proposed methodology, simulation experiments have been performed on cloud-aided active suspension systems.
