Disturbance observer-based adaptive reinforcement learning for perturbed uncertain surface vessels

Van Tu Vu et al.

Summary: This article discusses the issue of tracking and convergence in disturbance observer (DO) based optimal control design for uncertain surface vessels (SVs) with external disturbance. The proposed optimal control using adaptive/approximate reinforcement learning (ARL) considers the entire SVs with only one dynamic equation, eliminating the need for conventional separation technique. Additionally, the appropriate disturbance observer greatly reduces the attraction region of tracking error.

Fixed-Time Average Consensus of Nonlinear Delayed MASs Under Switching Topologies: An Event-Based Triggering Approach

Jian Liu et al.

Summary: This article addresses the fixed-time average consensus problem of nonlinear multiagent systems subject to various challenges, such as input delay, external disturbances, and switching topologies. An event-based control strategy is proposed to tackle this problem effectively, considering factors like nonlinear dynamics, external disturbances, and intermittent communication. The proposed approach reduces resource consumption significantly compared to continuous monitoring methods.

Gradient-based bearing-only formation control: An elevation angle approach

Liangming Chen et al.

Summary: This paper introduces a formation control method for multi-agent systems based on elevation angle rigidity theory, which attaches a rod or ball to each agent in 2D and 3D spaces to develop elevation angle rigidity. The control is achieved using only inter-agent bearing/direction measurements in agents' local coordinate frames.

Distributed online convex optimization with a bandit primal-dual mirror descent push-sum algorithm

Cong Wang et al.

Summary: This article addresses the distributed online convex optimization problem with time-varying constraints for multi-agent networks. It proposes the BDPDMDPS algorithm to optimize cost functions and constraint functions, and measures its operational performance in terms of expected regret and expected constraint violation. The algorithm is proven to have sublinear properties with respect to the total iteration span.

Summary: This study investigated the solution strategy for the space-fractional modified Cahn-Hilliard equation as a tool for gray value image inpainting model. A fast solver was developed for solving the linear systems arising from the 2D space-fractional modified Cahn-Hilliard equation. The theoretical analysis showed a fast convergence rate of the proposed preconditioner, which was confirmed in numerical examples.

Distributed constrained optimization problem of heterogeneous linear multi-agent systems with communication delays

Pin Liu et al.

Summary: This paper investigates the constrained distributed optimization problem of heterogeneous linear multiagent systems, where agents collaborate to minimize a global objective function by being subject to local set constraints, global nonlinear inequality constraints, and heterogeneous communication delays. By utilizing scattering transformation and a new distributed control law, the systems are proven to converge to the optimal solution.

Distributed Consensus-Based Economic Dispatch in Power Grids Using the Paillier Cryptosystem

Yamin Yan et al.

Summary: This paper proposes a novel secure scheme for the consensus-based economic dispatch algorithm using the Paillier cryptosystem, ensuring network transmitted information protection and privacy of each node. The proposed scheme relies on solving the structural consensus problem with time-varying network weights, and includes strategies for transmitting encrypted information, generating network weights with randomness, and addressing practical issues such as quantization error and computation overflow/underflow. Performance in cost optimization and privacy-preserving is verified by rigorous theoretical analysis and numerical simulation.
