Fault-tolerant control and disturbance rejection for impulsive switched systems with periodic intermittent faults

This article investigates fault-tolerant control and disturbance rejection for impulsive switched linear systems subject to periodic intermittent faults. First, a new periodic intermittent faults model is proposed, along with a Fourier series observer designed to accurately estimate faults and disturbances in the system. Next, a controller with disturbance rejection and fault-tolerant performance is designed based on these estimates. Stability is guaranteed under both arbitrary switching and average dwell-time strategies, and the correctness of this method has been demonstrated through numerical simulation and practical simulation.
