| Abstract: | 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. |
