An Efficient Calibration Method for Triaxial Gyroscope

نویسندگان

چکیده

This paper presents an efficient servomotor-aided calibration method for the triaxial gyroscope. The entire process only requires approximately one minute, and does not require high-precision equipment. is based on idea that measurement of gyroscope should be equal to rotation speed servomotor. A six-observation experimental design proposed minimize maximum variance estimated scale factors biases. In addition, a fast converging recursive linear least square estimation presented reduce computational complexity. simulation results reflect robustness under normal extreme conditions. We experimentally demonstrate feasibility robot arm, implement microcontroller. verify by comparing with traditional turntable approach, experiment indicates these two methods are comparable. By calibrated low-cost reading from gyroscope, we can conclude our significantly increases gyroscope’s accuracy.

ANFIS Approach for Tracking Control of MEMS Triaxial Gyroscope

In this paper, an Adaptive Neuro Fuzzy Inference System (ANFIS) based control is proposed for the tracking of a Micro-Electro Mechanical Systems (MEMS) gyroscope sensor. The ANFIS is used to train parameters of the controller for tracking a desired trajectory. Numerical simulations for a MEMS gyroscope are looked into to check the effectiveness of the ANFIS control scheme. It proves that the sy...

An Efficient Method for Model Reduction in Diffuse Optical Tomography

We present an efficient method for the reduction of model equations in the linearized diffuse optical tomography (DOT) problem. We first implement the maximum a posteriori (MAP) estimator and Tikhonov regularization, which are based on applying preconditioners to linear perturbation equations. For model reduction, the precondition is split into two parts: the principal components are consid...
