A communication mechanism is introduced that determines whether to transmit measurement values based on whether event-triggered conditions are violated, thereby minimizing redundant communication data. In designing the filter, noise decorrelation is initially conducted, followed by the integration of the event-triggered mechanism and the unreliable network transmission system for state estimator development. Subsequently, by combining the three-degree spherical\u2013radial cubature rule, the numerical implementation steps of the proposed state estimation framework are outlined. The performance estimation analysis highlights that by adjusting the event-triggered threshold appropriately, the estimation performance and transmission rate can be effectively balanced. It is established that when there is a lower bound on the packet dropout rate, the covariance matrix of the state estimation error remains bounded, and the stochastic stability of the state estimation error is also confirmed. Ultimately, the algorithm and conclusions that are proposed in this paper are validated through a simulation example of a target tracking system.<\/jats:p>","DOI":"10.3390\/s24030769","type":"journal-article","created":{"date-parts":[[2024,1,25]],"date-time":"2024-01-25T08:44:07Z","timestamp":1706172247000},"page":"769","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Event-Triggered State Filter Estimation for Nonlinear Systems with Packet Dropout and Correlated Noise"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1828-7161","authenticated-orcid":false,"given":"Guorui","family":"Cheng","sequence":"first","affiliation":[{"name":"Center for Control Theory and Guidance Technology, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9523-3402","authenticated-orcid":false,"given":"Jingang","family":"Liu","sequence":"additional","affiliation":[{"name":"Center for Control Theory and Guidance Technology, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3177-6701","authenticated-orcid":false,"given":"Shenmin","family":"Song","sequence":"additional","affiliation":[{"name":"Center for Control Theory and Guidance Technology, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1580","DOI":"10.1109\/TCYB.2018.2805717","article-title":"Adaptive consensus based distributed target tracking with dynamic cluster in sensor networks","volume":"49","author":"Zhang","year":"2019","journal-title":"IEEE Trans.
