Attack-Aware Event-Triggered Impulsive Control for Switched Nonlinear Systems via Multi-Diffeomorphism

This paper develops a unified hybrid control architecture for switched nonlinear systems under aperiodic denial-of-service (DoS) attacks with non-minimum phase internal dynamics. The methodology relies on three technical pillars: multi-diffeomorphism input-output linearization, a...

Hypokalemia leading to the diagnosis of primary Sjögren’s syndrome: the role of early renal biopsy

Abstract Background Hypokalemia due to distal renal tubular acidosis (dRTA) may represent the earliest manifestation of primary Sjögren’s syndrome (pSS), preceding the recognition of sicca symptoms. We report a case series highlighting the diagnostic challenges, renal manifestati...

Robust stability–guaranteed suboptimal decentralized control of interconnected nonlinear systems with structured parametric uncertainties

This paper presents a decentralized finite-horizon suboptimal control approach for uncertain interconnected nonlinear systems based on the decentralized finite-horizon state-dependent Riccati equation (DF-SDRE). The proposed method extends the classical state-dependent Riccati eq...
