Experimental-Based TGPID Motion Control for 2D CNC Machine
Abstract:
2D (two-dimensional) motion is the basic motion for computer numerical controlled (CNC) machine in all industrial applications. In this paper, it is aimed to optimize the multi-performance characteristics, namely roundness error determined by best-fit-circle (REB), actual radius (R_act) and position time (Tt) that is the time needed for making a circular motion. By applying a Taguchi Grey Proportional Integral Derivative (TGPID) control method, the performance of this 2D multi linear motion is improved. The roundness error is closed to zero as time went to infinity which means the actual radius is closed to the reference radius. The position time differences (dTt) of X and Y axis for circling is also zero. This indicated the TGPID approach is robust.
