摘要
提出一种简单但鲁棒性强的传感器动态建模方法,该方法基于数值积分思想,能有效克服测量噪声,无需迭代即可直接从微分方程辨识出模型参数,所建模型阶次较低、准确度较高,且较易实现递推算法,为传感器改善动态特性、实现动态补偿提供一种有效方法。大量实验和仿真结果验证了该方法的有效性。
A simple and very robust method is proposed for sensors' dynamic modeling. Based on numerical integrals, the model parameters are estimated from the differential equation without iterations, the method is very effective in overcoming large amounts of measurement noise in the output. The model's order built by this method is lower and the accuracy is higher.An effective method is proposed for improving sensors' dynamic characteristics and realizing sensors' dynamic compensation. The effectiveness of the identification method has been demonstrated through a number of simulations and tests.
