AI Technical Summary
When existing pneumatic servo control systems process sheet materials with periodic wavy patterns, the airflow transmission lag time is not fixed. This causes the controller's adjustment action to be superimposed on the actual pressure fluctuations, resulting in stripe defects on the sheet material surface and exacerbating the wear of mechanical parts.
By acquiring the control and response data of the polishing machine's grinding head in real time, feature extraction and matching are performed to determine the local ripple period and the measured response delay, and the PID parameters are dynamically adjusted to achieve compliant control.
It improves the control precision of the polishing machine's grinding head, reduces surface defects on the sheet metal, and extends the life of mechanical parts.
