The resulting conditions are subsequently used to constructively design distributed circle criterion estimators, which are able to collectively estimate an underlying linear system with a sector bounded nonlinearity.","authors_text":"Frank Allg\\\"ower, Jingbo Wu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2016-04-11T16:05:19Z","title":"Distributed Nonlinear Observer with Robust Performance - A Circle Criterion Approach"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1604.03014","kind":"arxiv","version":2},"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":"sha256:3dc291f3ee877ee93e11cb8dac9dc687a03aef322199525132b53be68a92e545","target":"record","created_at":"2026-05-18T01:17:16Z","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":"4d0eecc022f4683b931cb7aac82563eb5d4fe7e4fb899ae04cfba0d729b1eab9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2016-04-11T16:05:19Z","title_canon_sha256":"780790511abe767d1503846ca24a4cc40bda288f686174a9e87569f2dd70d31c"},"schema_version":"1.0","source":{"id":"1604.03014","kind":"arxiv","version":2}},"canonical_sha256":"fcf1f2c5d52864e8851f4f163cf9485bac536fb3c5f73596daa54edcd2bd4f88","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fcf1f2c5d52864e8851f4f163cf9485bac536fb3c5f73596daa54edcd2bd4f88","first_computed_at":"2026-05-18T01:17:16.508421Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:17:16.508421Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"j1FEbdJ5rsXkxMmrmA0ln/4Vt9DGyXmXKFrOPliIxNRZWEwsuIDu7oDKlRW6yUwifGGI6omuH0ueLdR4vuWWCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:17:16.509147Z","signed_message":"canonical_sha256_bytes"},"source_id":"1604.03014","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3dc291f3ee877ee93e11cb8dac9dc687a03aef322199525132b53be68a92e545","sha256:3169254efb3be873f88fe31abe1162ccc532216506ac056c9585f486fd5962e5"],"state_sha256":"7e1e2b698b88afd5e779bce5d1ff9a844764d5f2013c9acb5b678d7021b4a179"}
