Paper Title:
Research of Detector for Surface Defects of Steel Ball Based on Improved PID Control
  Abstract

This paper used digital image technology to detect surface defects of steel ball, and designed mechanism body and the corresponding control system. In order to improve the poor control effect of basic PID, we put forward modified PID control strategy, combining speed-variable integral, differential, and anti-saturation integral, then realized optimum design for PID parameters. The experimental results indicated that PID control strategy in the paper based on optimizing parameters had a maximum output at the initial time interval, so that the response speed of system would be much higher, and the adjusting time would also be shorter.
