Repetitive control considerably improves the accuracy of production processes with stationary disturbances by using predictive lag error compensation. Performance is increased considerably without a great deal of additional effort. A license is required to use this function on the ACOPOS P3.
- Drive units with position-dependent disturbances
- Drive units with virtually steady speeds
- Printing presses, filling systems, machine tools
When position-controlled drives run at constant speed, mechanical conditions can cause stationary disturbing torque fluctuations, which are generally observed as lag error localized to a certain area. Embedded in the standard speed control loop, the repetitive control function adjusts the drive's torque setpoint to drastically reduce the periodic portions in the speed and lag error. The algorithm undergoes a constant learning process so that changes to the load profile (e.g. caused by wear) have no effect whatsoever on the drive. The disturbance torque is compensated for predictively.
