Robust design of inertial measurement units based on accelerometers / Zhongkai Qin in Transactions of the ASME . Journal of dynamic systems, measurement, and control, Vol. 131 N° 3 (Mai 2009)

Titre : Robust design of inertial measurement units based on accelerometers Type de document : texte imprimé Auteurs : Zhongkai Qin, Auteur ; Luc Baron, Auteur ; Lionel Birglen, Auteur Année de publication : 2009 Article en page(s) : 07 p. Note générale : dynamic systems Langues : Anglais (eng) Mots-clés : inertial  measurement  unit;  accelerometers Résumé : This paper presents a robust design scheme for an inertial measurement unit (IMU) composed only of accelerometers. From acceleration data measured by a redundant set of accelerometers, the IMU proposed in this paper can estimate the linear acceleration, angular velocity, and angular acceleration of the rigid-body to which it is attached. The robustness of our method to the uncertainty of the locations of the sensors and the measurement noise is obtained through redundancy and optimal configuration of the onboard sensors. In addition, the fail-diagnostics and fail-safe issues are also addressed for reliable operation.
