Abstract

This paper addresses fault-tolerant control and disturbance rejection for linear systems with actuator saturation and communication constraints. A method based on the Fourier series is proposed to handle the non-differentiability of periodic intermittent faults at jump points. A window function is used to reduce the Gibbs phenomenon and a criterion for selecting the expansion order is provided. By designing a dynamic event-triggered composite observer, system states, faults, and disturbances are estimated simultaneously while reducing the communication burden. The effects of actuator saturation are handled using a dynamic anti-saturation compensator combined with L2 gain, and a fault-tolerant controller is developed based on the estimated information. Finally, the effectiveness of the proposed scheme was validated through a numerical simulation and a practical example.
