Fault-Tolerant Control for Systems With Unmatched Actuator Faults and Disturbances [PDF]
IEEE Transactions on Automatic Control, 2021 A fault-tolerant control (FTC) scheme for a class of nonlinear systems with unmatched actuator redundancy and unmatched disturbances is proposed in this note. A methodology to construct unified smooth sliding mode control laws and update laws is proposed such that the equivalent injections of the first-order time derivatives of the unmatched actuator ...
