| Abstract |
|
Design and implementation methodologies on the performance evaluation system of Two-channel Ring-Gate Compass (TCRC FG-Compass) are described, with evaluation procedures and methods based on the polynomial regression models. Performance evaluation system consists of a step motor driving unit, a bearing transmitting unit and evaluation programs derived from polynomial regression formulae. Newly designed performance evaluation system enabled the accuracy of TCRC FG-Compass to be ascertained. It was confirmed that the size of residual deviation of TCRC FG-Compass is 2°, while that of the conventional one is 4°. In addition, the design methodology to the self estimation and correction of residual deviations is also discussed. |
