摘要

本文的主要动机是提出一种精确而通用的非线性系统建模方法。提出了一种无约束贝塞尔校正方法。通过约束UBCM的边界自由度,它可以成为一种被称为Bezier校准方法(BCM)的约束形式,适用于有精确边界建模要求的情况。通过几个非线性行为建模实例,包括传感器固有非线性校准、正弦波、高斯非线性和非线性折线,将所提出的方法与应用最广泛的多项式校准方法(PCM)进行了比较研究。比较研究表明,在当前的验证示例中,UBCM比BCM和PCM具有更好的校准性能。

Unconstrained Bezier Calibration Method for Nonlinear Measurement Calibration Applications: A Comparison Study
The primary motivation of this paper is to present an accurate and universal method for the nonlinear system modeling. An Unconstrained Bezier Calibration Method (UBCM) is presented. By constraining the boundary freedom of the UBCM, it could become a constrained form called the Bezier Calibration Method (BCM), which is suitable for situations with an accurate boundary modeling requirement. A comparison study is performed to compare the presented method with the most widely utilized Polynomial Calibration Method (PCM) through several nonlinear behavior modeling examples, including sensor inherent nonlinearity calibration, sine wave, gauss nonlinearity and nonlinear broken line. A comparison study demonstrates that in the present verification examples the UBCM has better calibration performance than that of the BCM and PCM.
