| Summary: | 碩士 === 逢甲大學 === 資訊電機工程碩士在職專班 === 97 === This article studies the development of the axial
positioning errors into an analysis system, applied to the machine axial error measuring. To this end, first of all, the use of high-precision instruments set up online real-time measurement system on the machine, from the measurement of positioning errors during the data obtained.
Combination of neural networks can be analyzed to establish a mathematical model .First , Using laser interference equipment HP5529A and DAQ data capture meter to get the axis position error data and the ball screw totallength extending data . Then through by curve fitting method and system identification toolbox to create the error model . Finally , using the Neural Network reference control to result the error analyze , we can know the position error changing just like forecasted , which quit similar to the ball screw total length extending quantity . Also can create a useful Analysis model .
