The estimation scheme is designed in order to account, in a rigorous fashion, for dynamic coupling terms between subsystems, and for the uncertainty related to the state estimates performed by the neighboring subsystems. The online implementation of the proposed estimation scheme is scalable, since it involves (i) small-scale matrix operations to be carried out by the estimator embedded in each subsystem and (ii) neighbor-to-neighbor transmission of a limi","authors_text":"Marcello Farina, Ruggero Carli","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2015-07-24T12:13:28Z","title":"Partition-based Distributed Kalman Filter with plug and play features"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1507.06820","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0b7af785ed84f7651c020cdd099720247b4ee7bdbb8c48b7cd51c12ad1371665","target":"record","created_at":"2026-05-18T01:36:21Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"32931037a69a0585efccfcd6a812ad6832f48d9cb8be3cd66540bbe7f57242bc","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2015-07-24T12:13:28Z","title_canon_sha256":"27a8857ff878cd5aab82bf6c38ad269394a3eaa613907d96e133f433d0cf9eea"},"schema_version":"1.0","source":{"id":"1507.06820","kind":"arxiv","version":1}},"canonical_sha256":"bebfcca15e200f41f8ea77a8b1b9a18891894db84805f896a6653da22d14e5af","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bebfcca15e200f41f8ea77a8b1b9a18891894db84805f896a6653da22d14e5af","first_computed_at":"2026-05-18T01:36:21.942184Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:36:21.942184Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5xcPDB1NjtwQvpQ5kI69PHlZt5YNQGNb/5k1444BjWbhDZbieiCt9m9T4SC8xN1nkcdneKbOHR+WbvUFJLNoBA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:36:21.942745Z","signed_message":"canonical_sha256_bytes"},"source_id":"1507.06820","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0b7af785ed84f7651c020cdd099720247b4ee7bdbb8c48b7cd51c12ad1371665","sha256:a79cc3d2581a5086a62d5cd4f41804e00b179aadf052b40a6f1d776f35632366"],"state_sha256":"ecbe24854d8c76efdd79ba904de8b66111ca66d0bef8a64fa2eae017b37e021b"}
