To resolve these problems, a multi-model combined filter with dual uncertainties is proposed to integrate the outputs from numerous gyroscopes. First, to avoid the limitations of the stochastic and set-membership approaches and to better utilize the potentials of both concepts, a dual-noise acceleration model was proposed to describe the angular rate. On this basis, a dual uncertainties model of gyro array was established. Then the multiple model theory was used to improve dynamic performance, and a multi-model combined filter with dual uncertainties was designed. This algorithm could simultaneously deal with stochastic uncertainties and set-membership uncertainties by calculating the Minkowski sum of multiple ellipsoidal sets. The experimental results proved the effectiveness of the proposed filter in improving gyroscope accuracy and adaptability to different kinds of uncertainties and different dynamic characteristics. Most of all, the method gave the boundary surrounding the true value, which is of great significance in attitude control and guidance applications.<\/jats:p>","DOI":"10.3390\/s19010085","type":"journal-article","created":{"date-parts":[[2018,12,27]],"date-time":"2018-12-27T11:29:43Z","timestamp":1545910183000},"page":"85","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Multi-Model Combined Filter with Dual Uncertainties for Data Fusion of MEMS Gyro Array"],"prefix":"10.3390","volume":"19","author":[{"given":"Qiang","family":"Shen","sequence":"first","affiliation":[{"name":"Xi\u2019an Research Institute of Hi-Tech, Hongqing Town, Xi\u2019an 710025, China"}]},{"given":"Jieyu","family":"Liu","sequence":"additional","affiliation":[{"name":"Xi\u2019an Research Institute of Hi-Tech, Hongqing Town, Xi\u2019an 710025, China"}]},{"given":"Xiaogang","family":"Zhou","sequence":"additional","affiliation":[{"name":"Xi\u2019an Research Institute of Hi-Tech, Hongqing Town, Xi\u2019an 710025, China"}]},{"given":"Lixin","family":"Wang","sequence":"additional","affiliation":[{"name":"Xi\u2019an Research Institute of Hi-Tech, Hongqing Town, Xi\u2019an 710025, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2129","DOI":"10.1109\/JSEN.2017.2663420","article-title":"Utilizing gyroscopes towards the automatic annotation of seismocardiograms","volume":"17","author":"Yang","year":"2017","journal-title":"IEEE Sens.
