TL;DR: In this article, an adaptive fault tolerant attitude control method is presented for satellites with both time-varying actuator faults and multiple disturbances, where a composite observer is designed to estimate the uncertain modelled disturbance and the time varying fault simultaneously, and a new fault tolerant control strategy consisting of disturbance observer based control, fault accommodation and an adaptive controller is constructed to reconfigure the concerned systems and so as to achieve the anti-disturbance performance.

TL;DR: A new proportional-integral tracking control strategy for non-Gaussian stochastic systems based on a square root B-spline model for the output probability density functions (PDFs) is presented, with the peak-to-peak measure index applied to optimise the tracking performance.

TL;DR: An adaptive fault tolerant control approach based on disturbance observer is presented for attitude control system (ACS) with actuator faults, elastic modal, modeling error and environmental disturbance torque in this paper.

TL;DR: The fuzzy frequency-selecting sliding mode controller is applied to a 240 W all-digital adaptive dimming power supply prototype, which can effectively reduce the steady-state error of the output power of the LLC resonant converter, and has a consistent low ripple characteristic when the load changes.

TL;DR: In this paper, an anti-disturbance fault diagnosis scheme is addressed for a class of systems with both faults and multiple disturbances, where a composite observer with adaptive compensation is designed to estimate the uncertain modeled disturbance and fault simultaneously.
