Resilient fuzzy stabilization is capable of providing much less conservative results than conventional while the alert threshold condition should be always satisfied at each sampling instant. In order to make more easily guaranteed, short paper employs switching-type gain-scheduling control law so that real-time information, which specific current instant, can integrated into resilient stabilization. More importantly, a new kind time-variant balanced matrix introduced for first time...
This paper aims to develop a dynamic-memory event-triggered mechanism (DMETM) for Takagi-Sugeno (T-S) fuzzy switched systems under denial-of-service (DoS) attacks. Persistent dwell-time (PDT) is used describe the characteristics of both DoS attacks and switching behaviours. The usage PDT allows high-frequency attacking phenomenon during certain intervals. Meanwhile, DMETM designed screen more effective triggering instants reduce signal transmission frequency. dynamic conditions vary based on...
This paper proposes a novel dynamic event-triggered mechanism (DETM) of switched linear DC microgrid with intermittent denial-of-service (DoS) attacks. In system based on DETM, the subsystem mode is immediately updated along occurrence switching signals, while controller after successful event-triggering. means both communication interruptions and periodic sampling may cause asynchronous situations, which together pose challenge for stability analysis. To this end, multiple Lyapunov function...
To address the problem that difficulty of selecting parameters in XGBoost model makes it difficult to optimize regression effect, a short-term load forecasting based on sparrow search algorithm is proposed.

Taking data region Zhejiang Province from...
This paper presents a single bit continuous time delta-sigma modulator (CTDSM) with finite impulse response (FIR) feedback DAC designed for audio applications. By using FIR in the input stage, linearity requirements of first integrator are relaxed, and clock jitter sensitivity is reduced, as seen multi-bit quantizers. The choppers, working conjunction DAC, effectively suppresses in-band aliasing noise generated by chopper integrator. A fast comparator serves single-bit quantizer, 9.2% TS...
Abstract The effective regulation and storage of water resources by reservoirs in arid semi-arid areas is important for alleviating resource shortages.

Constant current-constant voltage (CC-CV) charging and pulse current are the usual methods for Li-ion batteries. Because we lack of direct in-situ measurement battery's internal state, both two controlled without feedbacks from inside battery.
