摘要
本文采用带时变噪声估计器的推广Kalman滤波方法,对长输管道的状态进行估计,并在此基础上,采用一定的诊断机制,实现对长输管道的泄漏诊断。实验结果表明,这种方法是有效的。
An application method of using the generalized Kalman filter with a time-varying noise estimator to estimate the states of pipelines (non-linear distributed parameter systems) is presented in this paper. The method is further developed to detect leakage and its location. Results obtained from a test on a liquid pipeline of a length of 120m and a inner dia. of 10mm have shown the effectiveness of the method.
