Abstract
En 中文
The paper develops two multiple faults-tolerant control (MFTC) frameworks via fully actuated system (FAS) approaches. Starting from the observable space related to each measurement, the first MFTC structure provides a fusion estimation of high-order state and actuator faults. Under a fault detection logic based on the dynamical sensor index, the MFTC strategy can effectively accommodate unbounded sensor faults. In view of the noise effect on high-order systems, a saturated observer is redesigned in the second MFTC. One last thing, the proposed observer-saturated MFTC framework has better noise suppression performance. The system stability is theoretically proved and experimentally illustrated.
