Abstract
AbstractThis paper addresses the security issue of networked control systems (NCSs) under DoS attacks. According to the level of attacks, DoS attacks are classified into two types: weak attacks and strong attacks. A recursive networked predictive control (RNPC) method based on round-trip time delay is proposed to compensate for the adverse effects introduced by the weak DoS attacks as well as the network communication constraints, such as random delay, packet disorder and packet loss. A theoretical result using the switched system theory is also obtained for the closed-loop stability of the RNPC system. For the strong DoS attacks on the controller side, a multi-controller switching scheme is presented, in which each controller is designed based on the RNPC. The performance of the proposed strategies is demonstrated by practical experiments to control a DC motor speed through the Internet under DoS attacks.
