Based on the hypothesis test of Gaussian distribution, the significance of the event-triggered threshold is given. Based on the threshold, the actual trigger frequency of the estimated system can be accurately set. Combining the threshold and the proposed event-triggered mechanism, an event-triggered Kalman filter is proposed and the approximate estimation accuracy can also be calculated. Whether it is a steady system or a time-varying system, the proposed algorithm can reasonably set the threshold according to the required accuracy in advance. The proposed event-triggered estimator not only effectively reduces the communication cost, but also has high accuracy. Finally, simulation examples verify the correctness and effectiveness of the proposed algorithm.<\/jats:p>","DOI":"10.3390\/s23042202","type":"journal-article","created":{"date-parts":[[2023,2,16]],"date-time":"2023-02-16T01:36:52Z","timestamp":1676511412000},"page":"2202","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Event-Triggered Kalman Filter and Its Performance Analysis"],"prefix":"10.3390","volume":"23","author":[{"given":"Xiaona","family":"Li","sequence":"first","affiliation":[{"name":"School of Electronic Engineering, Heilongjiang University, Harbin 150080, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1252-5771","authenticated-orcid":false,"given":"Gang","family":"Hao","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering, Heilongjiang University, Harbin 150080, China"},{"name":"Key Laboratory of Information Fusion Estimation and Detection, Harbin 150080, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"100","DOI":"10.1016\/j.ins.2017.04.042","article-title":"Gradient-driven parking navigation using a continuous information potential field based on wireless sensor network","volume":"408","author":"Wei","year":"2017","journal-title":"Inf.
