Engineering Contradiction Analysis
1Measurement precision
If ANN methodology is used for oscillator compensation, then curve fit quality is improved, but solution time increases significantly and reliability decreases
Solution Approach 1:
The patent segments the test data set into multiple segments based on user-defined criteria, applying different polynomial functions to each segment. This segmentation approach divides the complex curve fitting problem into manageable parts, achieving both high precision and reliability without the computational burden of ANN methodologies.

Solution Approach 1:
The patent changes the parameters of polynomial functions (order, coefficients, segment boundaries) to achieve desired performance precision. This approach provides precise control over compensation performance without the exponential complexity increase associated with adding neurons to neural networks, maintaining device simplicity while achieving high precision.
