Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-axis control systems face challenges in efficiently adjusting control parameters across multiple axes, particularly in scenarios where axes are mechanically constrained or not, leading to issues with vibration and oscillation, which can damage machinery and affect synchronization accuracy.
Innovation Solution
A multi-axis control adjustment apparatus and method that selects target axes, performs adjustment operations based on common or individual commands, and adjusts the timing of control parameter setting to ensure synchronized and accurate parameter adjustment, regardless of mechanical constraints, using a parameter adjustment apparatus with axis selection, operation execution, and control parameter setting units.

Engineering Contradiction Analysis
1Productivity
If control parameters are adjusted for multiple axes simultaneously, then productivity is improved, but synchronization accuracy deteriorates due to timing differences in parameter setting
Solution Approach 1:
The system performs preliminary actions by calculating and preparing adjusted control parameters for all target axes before actual adjustment execution. The host controller computes the adjusted parameters based on the relationship between axes, and stores them ready for simultaneous application, ensuring that all axes receive their adjusted parameters at the same timing without sequential delays
Solution Approach 2:
The system merges the parameter adjustment operations for multiple axes into a single simultaneous execution. By combining the adjustment operations and applying all adjusted control parameters to the target axes at the same timing through the host controller, the system achieves both high productivity and maintained synchronization accuracy
2Adaptability or versatility
If control parameters are adjusted without considering mechanical constraints, then adaptability is improved, but harmful factors increase due to vibration and oscillation
Solution Approach 1:
The system incorporates feedback by detecting whether mechanical constraint relationships exist between axes before performing adjustment operations. The host controller determines the presence of mechanical constraints based on system configuration information, and uses this feedback to decide whether to execute simultaneous multi-axis adjustment or individual axis adjustment, thereby preventing vibration and oscillation while maintaining adjustment flexibility
Solution Approach 2:
The system dynamically adapts its adjustment strategy based on the detected mechanical constraint conditions. When mechanical constraints are detected, the system switches to individual axis adjustment to prevent harmful vibrations. When no mechanical constraints exist, it employs simultaneous multi-axis adjustment for higher efficiency. This dynamic adaptation allows the system to maintain versatility while avoiding harmful factors
