Integration of visual and antennal mechanosensory feedback during head stabilization in hawkmoths
eLife, 2022 During flight maneuvers, insects exhibit compensatory head movements which are essential for stabilizing the visual field on their retina, reducing motion blur, and supporting visual self-motion estimation.

Observer-Based Finite-Time H∞ Control of Singular Markovian Jump Systems
Journal of Applied Mathematics, 2012 This paper addresses the problem of finite-time H∞ control via observer-based state feedback for a family of singular Markovian jump systems (SMJSs) with time-varying norm-bounded disturbance.

Vertical displacements close to ideal-MHD marginal stability in tokamak plasmas
Fundamental Plasma Physics, 2023 Elongated tokamak plasmas are prone to instability, initiated by vertical displacement perturbations, which can be suppressed if a perfectly conductive wall is placed near the plasma boundary, providing passive feedback stabilization.

Feedback Stabilization and Lyapunov Functions [PDF]
SIAM Journal on Control and Optimization, 2000 The authors consider the problem of finding a feedback stabilizing law \(x \to k(x)\) associated with a control system \(x'(t) = f(x(t),u(t))\). Using the concept of positional strategies introduced in the framework of differential games by Krasovskii and Subbotin in 1988, assuming the existence of a Lyapunov Lipschitz function \(V\) defined on the ...

High-resolution, low-latency, bunch-by-bunch feedback system for nanobeam stabilization
Physical Review Accelerators and Beams, 2022 We report the design, operation, and performance of a high-resolution, low-latency, bunch-by-bunch feedback system for nanobeam stabilization. The system employs novel, ultralow quality-factor cavity beam position monitors (BPMs), a two-stage analog ...

Building a Total Internal Reflection Microscope (TIRF) with Active Stabilization (Feedback SMLM)
Bio-Protocol, 2021 The data quality of high-resolution imaging can be markedly improved with active stabilization, which is based on feedback loops within the microscope that maintain the sample in the same location throughout the experiment.

IEEE Access, 2020 This paper studies a separation principle for a class of linear sampled-data control systems with aperiodic sampling. The concerned problem is to show that in aperiodic sampling, the design of observer-based output feedback controller can be broken into ...
