Monitoring of drive control loops in computer-controlled machine tools or industrial robots

摘要

The invention relates to the dynamic control-loop monitoring in computer-controlled machine tools. Using a discreet point-to-point model (3) which is stored as differential equation in the computer (1), actual values (xist) are calculated and compared with the real actual values (xist). Deviations exceeding a particular tolerance band allow errors in the point-to-point section to be inferred. IMAGE
