| 英文摘要 |
| In this paper, we study the memory-based event-triggered predictive control of networked control systems
(NCSs) under DoS attacks. First, due to the limited network bandwidth resources and incomplete observability of the
system state, a memory-based event-triggered function is introduced to provide a discrete event-triggered transmission
scheme for the observer. Then, the DoS attacks occurring on the network transmission channel are analyzed. Combining
the above memory-based event-triggering scheme, a novel class of predictive control algorithms is designed at the control
node to save the network bandwidth resources and actively compensate for DoS attacks. Meanwhile, a closed-loop system
of observer memory-based event-triggered predictive control is established and analyzed for stability. The design scheme
of controller, observer and memory-based event-triggered matrix is established by linear matrix inequality (LMI) and
Lyapunov stability theory, and the feasibility of the scheme is analyzed. The simulation results show that the scheme
combined with the memory-based event-triggered mechanism can effectively compensate for the DoS attacks and save the
network bandwidth resources. |
