Robust Control Methods for Coping with Cyber Interference and Physical Uncertainty in Cyber-Physical Systems

Cyber-physical systems (CPSs) are a kind of systems integrating cyber and physical components, which may be subject to physical uncertainty and cyber interference in the process of operation. In order to solve this problem, a new control design method is proposed by studying the constrained following problem of controlled systems under physical uncertainty and cyber interference. The remarkable feature of this control is that both physical uncertainty and cyber interference are taken into account, which ensures that the controlled system can resist cyber interference while still meeting the expected constraints. In addition, the effectiveness and superiority of the proposed control method are verified by the simulation comparison with sliding mode control (SMC) in the autonomous vehicle scenario.
