A controller is first designed for the ideal situation assuming the uncertain parameter was known and it renders a Lyapunov function. Then, the uncertain parameter in the controller is replaced by its estimation that is updated by an adaptive law along the gradient of Lyapunov function. This principle does not generally work for a multi-agent system as an adaptive law based on the gradient of (centrally constructed) Lyapunov function cannot be implemented in a distributed fashion, except for","authors_text":"Imil Hamda Imran, Lijun Zhu, Minyue Fu, Zhiyong Chen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2019-04-25T03:18:59Z","title":"A Distributed Adaptive Scheme for Multi-Agent Systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1904.11137","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:e7ce10bd71fe167515a076fe0a17a98aced199019ca617248aaeb962dd17da4b","target":"record","created_at":"2026-05-17T23:47:45Z","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":"93d47b91dd93673823f7661453108d8584bfa61c470b3e497d7fdb377e96636a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2019-04-25T03:18:59Z","title_canon_sha256":"f5557aff576949900a2692dd11b173076a884bfde3230a857f1fe191b5f33a82"},"schema_version":"1.0","source":{"id":"1904.11137","kind":"arxiv","version":1}},"canonical_sha256":"77d03382d866f49f087cdc514fe39bfb9c1bed37040d80e8aacbc976a48eda7d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"77d03382d866f49f087cdc514fe39bfb9c1bed37040d80e8aacbc976a48eda7d","first_computed_at":"2026-05-17T23:47:45.677981Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:47:45.677981Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"oVU+coyXhoP+UB9447IVkeKGPMOCAWo5kGBWJGioXD/1MbM6qSkWuPSIelhD5zgJAYoqnE7beV51RAaEgZIOBQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:47:45.678507Z","signed_message":"canonical_sha256_bytes"},"source_id":"1904.11137","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e7ce10bd71fe167515a076fe0a17a98aced199019ca617248aaeb962dd17da4b","sha256:95a5114d0ee69aa41f4c97ed4982303dd7cd11486458d965dffa9cbe916c84e4"],"state_sha256":"c12541a57fadb39aa0e46b1b9cd457560ac27a1c19b2ba0b043e528b96b72b1d"}
