PUBLISHED ON IEEE/ASME TRANSACTIONS MECHATRONICS, DOI: 10.1109/TMECH.2021.3100150. Ideally, accurate sensor measurements are needed to achieve a good performance in the closed-loop control of mechatronic systems. As consequence, faults will prevent system from working correctly, unless fault-tolerant (FTC) architecture is adopted. model-based FTC algorithms for nonlinear systems often challengi...
