リニアパルスサーボモータの繰り返し位置決め制御特性とその改善

抄録

This study aims to realize high precision repetitive positioning control of a linear pulse servo motor. By using this method the systematic error which may makes the precision worse can be suppressed easily. And also it shows that Power OP-Amp drive system enables the random error to be suppressed in comparison with PWM control drive system using IGBT inverter. As a result of the suppression of systematic and random error, improved performance of a linear pulse servo motor with repetitive positioning control is shown by experimental results. Moreover, the study examines the repeatability positioning precision of variable distance repetitive positioning control, other than the conventional equal distance positioning.
