Distributed Coordination Algorithms with Efficient Communication for Open Multi-Agent Systems with Dynamic Communication Links and Processing Delays: Extended Version
Jiaqi Hu, Karl H. Johansson, Apostolos I. Rikos
In this paper we focus on the distributed quantized average consensus problem in open multi-agent systems consisting of dynamic directed communication links among active nodes. We…
Soft Actor-Critic with Backstepping-Pretrained DeepONet for control of PDEs
Chenchen Wang, Jie Qi, Jiaqi Hu
This paper develops a reinforcement learning-based controller for the stabilization of partial differential equation (PDE) systems. Within the soft actor-critic (SAC) framework, we…
Neural Operator based Reinforcement Learning for Control of first-order PDEs with Spatially-Varying State Delay
Jiaqi Hu, Jie Qi, Jing Zhang
Control of distributed parameter systems affected by delays is a challenging task, particularly when the delays depend on spatial variables. The idea of integrating analytical cont…
Neural Operator Feedback for a First-Order PIDE with Spatially-Varying State Delay
Jie Qi, Jiaqi Hu, Jing Zhang +1
A transport PDE with a spatial integral and recirculation with constant delay has been a benchmark for neural operator approximations of PDE backstepping controllers. Introducing a…
Max-Consensus with Deterministic Convergence in Directed Graphs with Unreliable Communication Links
Apostolos I. Rikos, Jiaqi Hu, Themistoklis Charalambous +1
We present DMaC, a novel distributed, finite-time algorithm that guarantees max-consensus in directed networks with unreliable communication links experiencing packet drops. Unlike…
