NDLI: Finite-time robust fault-tolerant control against actuator faults and saturations

Content Provider	IET Digital Library
Author	Jin, Xiao Zheng He, Yi Gang He, You Guo
Abstract	The finite-time robust fault-tolerant control problem is addressed for a class of perturbed linear systems with actuator faults and input amplitude saturations. A compensation control strategy is proposed to eliminate the effects of actuator faults and non-linear disturbance-like inputs within a finite-time, as well as to ensure the control inputs be limited within a desired constraint. Based on Lyapunov stability theory, it is shown that system states can converge to a small region in the cases of actuator faults and saturations by choosing suitable control parameters. Some relationships among convergence bounds, actuator faults and amplitude limits, as well as the control parameters are studied deeply and illustrated explicitly with formulas. Simulations of a linearised F-18 longitudinal dynamical control model are given to verify the effectiveness of the proposed method.
