| Summary: | 碩士 === 中華大學 === 電機工程學系(所) === 96 === In this thesis, the aggressive moving average with an exogenous input (ARMAX) is adopted to model the aiming trajectory recorded during the last 1.5 second before releasing the arrow. Some useful variables related to the model are defined for analyzing the performance of archers. Through the statistic correlation approach, the individual and grouping characteristics are anticipated to be obtained from it. During that 1.5 period, the desired adjustments of archers without consideration their muscle strength are the main interest in this thesis. For expertise archers, their desired aiming style should not contain high frequency which is corresponding negative pole of the model. Therefore, a Hamming window is implemented to remove the high frequency effect. The expected coupling effect between both axes is confirmed. The direct effect on the performance related to these variables has been discussed, and the low correlation requirements among these variables for better performance are also outlined for further use. Some conceivable suggestions for individual are presented in the thesis.
