This paper investigates the autocalibration of microelectromechanical systems (MEMS) triaxial accelerometer (TA) based on experimental design (DoE). First, for a special 6-parameter second-degree model, a six-point experimental scheme is proposed, and its G-optimality has been proven based on optimal DoE. Then, a new linearization approach is introduced, by which the TA model for autocalibration can...
In this paper, we proposed a novel method for autocalibration of triaxial Micro-Electro-Mechanical systems (MEMS) accelerometer that does not require any sophisticated laboratory facilities. In particular, this method is an online calibration method which can be conveniently implemented with the accuracy of MEMS accelerometer being significantly improved. The procedure exploits the fact that the output...
This paper introduces a self-designed wearable inertial measurement unit (IMU-BMSJv2) and the calibration of its tri-axial accelerometers. We compare two popular accelerometer calibration approaches, the classical method (attitude dependent) and auto calibration method (attitude independent). Both these two calibration methods have been applied for the calibration of the self-designed IMU-BMSJv2;...
The calibration and its associated experimental design scheme for the tri-axial magnetometers are explored in this paper. For the widely used 9-parameter model of tri-axial Magnetometers, based on experimental design of Tri-axial accelerometers, a 12-observation experiment scheme, whose observations are located in the vertices of an icosahedron, is presented to reduce estimation error. As this 12-observation...
