Simultaneously, ensuring the stability is crucial for the robust identification of dynamic networks, especially under data and model uncertainties. To handle these challenges, this paper proposes a particle consensus-based expectation maximization (EM) algorithm. The E-step proposes a distributed particle filtering approach, using local observations from agents to yield global consensus state estimates. The M-step constructs a likelihood function with an a priori contraction-stabilization constraint for the parameter estimation of isomorphic agents. Performance analysis and simulation results of the proposed method confirm its effectiveness in identifying parameters for stable nonlinear networks.", "revisions": [ { "version": "v1", "updated": "2024-01-06T13:36:16.000Z" } ], "analyses": { "keywords": [ "stable large-scale isomorphic nonlinear networks", "partial observations", "multi-agent networks encounters challenges", "distributed identification", "yield global consensus state estimates" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
