This paper mainly discusses two kinds of coupled reaction-diffusion neural networks (CRNN) under topology attacks, that is, the cases with multistate couplings and with multiple spatial-diffusion couplings. On one hand, by adopting state feedback control scheme, the problem of the lag synchronization for the multistate coupled CRNN is addressed. Moreover, the influences of external disturbances for the lag synchronization of the CRNN with multistate couplings are also taken into consideration. On the other hand, several lag and lag H∞ synchronization conditions for CRNN with multiple spatial-diffusion couplings are derived under the help of the Kronecker product and the state feedback control method. Finally, two numerical examples are provided to verify the correctness of the derived criteria. © 2014 IEEE.

When we face a complex, evolving artificial system, there are "rational" individuals in the system who pursue their own interests. This paper we regulate the individuals in order to avoid significant pitfalls. First, we introduce hierarchical structure model of a game-based control system for macro-regulation and formulate the model by forward differential equation. Then we analyze the system with the extreme value principle and give the unique solution known as the Nash equilibrium. Moreover, we converse the model to the forward and backward equation to study the necessary and sufficient condition on the controllability of the system. Finally, we give the dual model of the system to study the observability inequality.

Autonomous collaborative decision-making is the key technology to achieve large-scale unmanned combat. Focus on the problem of multiple unmanned aerial vehicles' cooperative decision in target offensive and defensive combat, a multi-agent deep reinforcement learning (MADRL) based decision framework is proposed in this paper. Firstly, the simulation environment with a high-fidelity fixed-wing motion model is built. Secondly, to address the issue of high-dimension state space and credit assignment under a multi-agent environment, an enhanced multi-agent proximal policy optimization with mean-field counterfactual advantage (MAPPO - MFCOA) is proposed. Finally, the results of simulation experiments will verify the performance of the proposed approach. © 2023 Technical Committee on control Theory, Chinese Association of Automation.

The volume of existing metamaterial absorber (MMA) is not small enough to be applied in miniaturized devices such as chip level. To solve this problem, a miniaturized ultrathin wide-band MMA is proposed in this paper. The thickness of proposed MMA is 1.1mm with a absorption rate of 99.6% at 19.7GHz. This paper also analyzes the influence of parameters of the proposed MMA on the absorption performance and proves that it has a certain tunability of the absorption band. By comparing with other works, the MMA proposed in this paper realizes the miniaturization of the structure while ensuring ultra-wideband. This benefit offers a novel approach to address the problem of difficult loading electromagnetic shielding structures in miniaturized chip designs. © 2023 Applied Computational Electromagnetics Society (ACES).
