Robust MPC for actuator-fault tolerance using set-based passive fault detection and active fault isolation [PDF]
, 2014 In this paper, an actuator fault-tolerant control (FTC) scheme is proposed, which is based on tube-based model predictive control (MPC) and set-theoretic fault detection and isolation (FDI). As a robust MPC technique, tube-based MPC, can effectively deal

Fault Detection With LSTM-Based Variational Autoencoder for Maritime Components
IEEE Sensors Journal, 2021 Maintenance routines on ships today follow either a reactive maintenance (RM) or preventive maintenance (PvM) approach. RM can be regarded as post-failure repair, which might create large costs.
