静电校准是卡西米尔力测量中的重要环节。这对于系统参数的估计，如绝对分离距离和静电力模型的辨识是必要的。正确估计未知参数和静电力模型是解释卡西米尔力数据的关键。本文提出了一种具有较高灵敏度和鲁棒性的静电校准方法。它是基于大幅度动态力测量。理论上证明了该方法可以准确地求出系统的未知参数，并能辨识出静电力模型。当Casimir力测量在球体和平面之间进行时，我们的方法的有效性和鲁棒性在添加噪声的合成数据上进行了测试。
Electrostatic calibration is important in Casimir force measurements. It is necessary for the estimation of the unknown system parameters such as the absolute separation distance and the identification of the electrostatic force model. Correct estimates of the unknown parameters and the electrostatic force model are crucial for interpreting the Casimir force data. In this paper, we present an electrostatic calibration method with higher sensitivity and robustness. It is based on large-amplitude dynamic force measurements. It is proven in theory that the unknown system parameters can be obtained accurately and the electrostatic force model can be identified by our method. The effectiveness and robustness of our method are tested on synthetic data with added noise when the Casimir force measurement is conducted between a sphere and a flat surface.
