Continuous Control Sensitivity Tuning for Stable Convergence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mathematical optimization methods for deriving optimal control values often lead to excessive movement and divergence of target devices due to minor improvements in control values, resulting in shortened lifespan and unreliable control systems.
Innovation Solution
A system for adjusting continuous control sensitivity based on optimal search, which calculates a control fare using a base fare and a distance fare, and selectively applies optimal control values only when the control gain is greater than or equal to a preset reference value, incorporating a load detector to adjust fares based on system load.

Engineering Contradiction Analysis
1Manufacturing precision
If mathematical optimization methods are used to derive optimal control values with minor improvement in objective function, then control precision is improved, but device lifespan is shortened due to excessive movement
Solution Approach 1:
The patent introduces a threshold parameter (reference value) for control gain to filter out minor improvements. By changing the parameter selection criteria from accepting any improvement to accepting only improvements above the threshold, the system avoids excessive device movement while maintaining control precision for significant optimizations.
Solution Approach 2:
The patent applies partial action by selectively applying control values only when the control gain exceeds the reference value. This prevents unnecessary control actions (excessive movement) while still achieving the necessary control adjustments, thereby extending device lifespan without completely sacrificing control precision.
2Manufacturing precision
If mathematical optimization methods are used to derive optimal control values with minor improvement in objective function, then control precision is improved, but control stability deteriorates due to divergence
Solution Approach 1:
The patent changes the acceptance criterion parameter from accepting all improvements to accepting only improvements above a threshold (reference value). This parameter change stabilizes the control system by preventing divergence caused by accumulating minor improvements, while still achieving precision through significant optimizations.
Solution Approach 2:
The patent implements feedback by calculating control gain and comparing it against a reference value before applying control adjustments. This feedback mechanism prevents divergence by filtering out control actions that would destabilize the system, thereby maintaining control stability while achieving precision through validated improvements.
3Manufacturing precision
If control values are derived even with minor improvement in objective function, then control precision is improved, but device lifespan is shortened
Solution Approach 1:
The patent modifies the control application parameter by introducing a reference value threshold for control gain. This changes the decision criterion from applying all control values to applying only those with sufficient improvement magnitude, thereby reducing unnecessary device movement and extending lifespan while maintaining precision for significant optimizations.
Solution Approach 2:
The patent applies partial action by selectively implementing control adjustments only when the control gain exceeds the reference value. This prevents excessive device movement caused by minor improvements while still achieving necessary precision through significant control actions, thereby extending device lifespan without completely sacrificing control precision.
