The application of total least squares method in the error model identification of PIGA
Based on all-round effect of error factor for PIGA, the paper establishes theoretical error models. Develops the testing of PIGA on the three- axes turntable, the analysis has shown that the input acceleration includes position error of the testing equipment. We use the testing data by the three- axes turntable to identify the error model of PIGA, and the total least squares method by the comparison with the least squares. The purpose of applying the total least squares method is to eliminate the influence of the testing equipment error to instrument precision, but the accuracy is superior to the least squares, which can enhance identification precision of the testing PIGA.
