Through analyzing the mechanism of the temperature drift and designing the experiment of verification, the temperature drift of HDRG can be effectively suppressed. It is demonstrated that the zero-rate bias (ZRB) of HDRG in turn-on period can reach 0.08 °/h (1σ) with self-calibrating method. Also, the bias stability of 1.85 °/h (1σ) is realized when the temperature is changed from 0 ℃ to 60 ℃ at the heating speed of 1 ℃/min. Interestingly, the phenomenon of nonlinear change of ZRB is observed at under variable temperature, which may be due to the thermal stress of the immature packaging of device or the modal coupling between different modes of MEMS resonator. Finally, the approach in this paper is also widely applicable to other vibration inertial sensors with symmetrical mode shapes, which may be useful for ZRB compensation on inertial sensors with high performance.","PeriodicalId":435781,"journal":{"name":"2022 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115431996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with the actual precision limitations of the silicon etching processes, some dispersion in the etching of the flexure springs may results in non-zero coupling stiffness between the X and Y-axis, which leads to a quadrature error. As the stiffness of the flexure springs highly depends on its width, it is necessary to investigate the impact of the local width dispersions on the stiffness coupling. In this paper we report on our approach, which is based on the use of Finite Element Analysis (FEA) to determine the evolution of the stiffness matrix of the springs of our gyroscope regarding the bending beam width imperfections. Based on our results, a statistical analysis is carried out in order to evaluate the mean and the standard deviation of the absolute value of the amplitude of the quadrature signal for a given beam width variation. Then, we compare our model to the actual quadrature error of our gyroscopes, which has been measured with a dedicated bench. It turns out that a bending beam width variation of 0.9% leads to a quadrature error discrepancy with the same order of magnitude that the one measured, emphasizing the importance of the consideration of the bending beams width variation during the dimensioning of MEMS gyroscopes, in order to avoid high quadrature error.","PeriodicalId":435781,"journal":{"name":"2022 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125948221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The outputs of four inclinometers (ST IIS2CLX), that are nominally identical and set with the same operative conditions, have been acquired for 48 h consecutively. Each acquired dataset has been studied separately employing the Overlapping Allan VARiance (OAVAR) analysis to identify the Velocity Random Walk (VRW) and the Bias Instability (BI) noise contributions. The DF approach based on ensemble averaging across samples has been then applied combining the four acquired datasets, thus creating new datasets DFn, that contain averaged output data of n inclinometers at each acquisition time. The VRW and BI noise contributions of the DFn datasets have been identified through the OAVAR analysis and compared with the noise contributions of single inclinometers. Experimental results have shown a reduction of the noise variance σ2n for both the BI and VRW with a factor 1/n or, equivalently, the noise deviation σn with a factor $1/sqrt n $, in good agreement with theoretical expectations.","PeriodicalId":435781,"journal":{"name":"2022 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127343978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
