Servo Control Device Stiffness Term Vibration Compensation

The patent employs iterative identification methods where the transfer function parameters are refined through multiple cycles of excitation, measurement, and parameter adjustment. The system continuously compares predicted vibrations with actual measurements and adjusts machine constants accordingly, transforming a difficult one-shot identification problem into a manageable iterative feedback process.

The patent utilizes mechanical vibration excitation to identify machine constants. By applying controlled vibrations to the system and measuring the response, the identification process can extract dynamic characteristics including stiffness and damping parameters. This vibration-based approach enables accurate identification of transfer function parameters that would be difficult to obtain through static measurements.

The patent segments the vibration compensation into multiple components: column vibrations and carriage characteristic vibrations. By creating separate transfer function models for each vibration source and their interactions, the system can independently identify and compensate for each type of vibration, thereby achieving comprehensive compensation coverage that a single unified model cannot provide.

The patent introduces an intermediary measurement system that captures both column vibrations and carriage vibrations separately. This intermediary measurement layer enables the identification of the complex interaction between column and carriage dynamics, allowing the compensation system to address characteristic vibrations that arise from the coupled system rather than treating them as a single undifferentiated phenomenon.
