Fuzzy linear extended states observer‐based iteration learning fault‐tolerant control for autonomous underwater vehicle trajectory‐tracking system

Abstract: To deal with thrusters' faults of autonomous underwater vehicle (AUV), an iterative learning algorithm fault-tolerant control (FTC) based on the linear extended states observer (LESO) is proposed. In this control scheme, the non-linear feedback mechanism of the LESO is transplanted into iterative learning processes to estimate fault. Compared to our previous work, LESO is used to substitute classic non-linear extended state observer to make the establishment of the whole system more structured; moreover, the n… Show more

“…How to extract fault features from this complex signal has always been the hot point problem of underwater thruster fault diagnosis. 10 Common fault diagnosis methods include the state observer, 11,12 hidden Markov model, 13,14 wavelet time-frequency analysis, 15 D-S evidence theory, 16 support vector machine, 17 and neural network. 18,19 The application of deep learning technology, such as neural network, to intelligent fault diagnosis of underwater thrusters has attracted the attention of researchers.…”

“…1 Unmanned underwater vehicles such as remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs) are ideal platforms for marine resources exploration. 2,3 AUVs have received more and more attention attributing to their ability to complete underwater missions without mother ship support and manual intervention. 4,5 Thrusters as universal power components are often used in AUVs.…”
