Calibration of accelerometer using fuzzy inference system

This paper is on measuring a reliable linear velocity using a fuzzy inference system (FIS) for an inertial navigation system (INS). A conventional INS has been utilized to measure yaw angle using a gyro sensor and linear velocity through an accelerometer. However, linear velocity is not accurate because an INS has problems which are error by sensor error and cumulating errors of the accelerometer. The proposed Fuzzy-INS (F-INS) using a FIS calibrates the raw data of an accelerometer using an encoder and a FIS. In experiment results, we verified that the proposed F-INS calibrates the raw data of an accelerometer effectively and outputs linear velocity.
