In this paper a solution for the multileak reconstruction issue is introduced using a sliding mode observer scheme. Since fluid model in a pressurized single pipeline with only known pressures and flows at the ends does not satisfy the sliding mode observer conditions for leak reconstruction, a cascade scheme to satisfy such conditions is proposed. The key of the proposal is the estimation of pressures at the leak points through successive estimations of internal states up to those in which faults affect. The performance of the technique and its robustness with respect to operation point changes after the leak occurrences are illustrated by simulated and experimental results. |
