  Abstract

This thesis proposes a center distributed embroidery machine with a maximum speed of 1,500 rpm, 52 productivity heads, and capability to produce large-sized embroidered goods. In addition, the use of a velocity and twoaxis synchronous position controller with a DOB (disturbance observer) is proposed for minimizing disturbances due to needle cams. Specifically, for the center distribution experiment, we used two conventional, 26-head, 1,500-rpm embroidery machines and showed that the proposed controller can ensure stable operation of the simulated 52-head embroidery needlework at 1,500 rpm.
