The Research of Circular Interpolation Motion Control Based on Rectangular Coordinate Robot
Abstract:
The high-speed pulse outputs of PLC can control motion of stepper motor or servo motor. So PLC can complete interpolation function which CNC can do using a kind of simple algorithm. What’s more, the PLC can be developed to be a controller of economical CNC machine tools. Based on the experiment platform of modern robot industrial, the paper introduced how to control the motion of servo system by PLC in detail, and completed the two-dimensional interpolation program through PLC using the direct target tracking as interpolation algorithm. The direct target tracking algorithm could form a series of micro straight line segments approach the desired interpolation trajectory through directly calculating a series of minimum interval points on the interpolation line and connecting these points end to end. Compared to the single pulse interpolation, the direct target tracking algorithm simplified interpolation algorithm and adapted to the PLC program, so it is suitable to economical CNC system. By programming and running in the experimental platform, it can achieve better results using the direct target tracking method as interpolation procedures.
