Simultaneous Water Vapor and Dry Air Optical Path Length Measurements and Compensation with the Large Binocular Telescope Interferometer [PDF]
, 2016 The Large Binocular Telescope Interferometer uses a near-infrared camera to measure the optical path length variations between the two AO-corrected apertures and provide high-angular resolution observations for all its science channels (1.5-13 $\mu$m ...

Frontiers in Energy Research, 2022 Although the stability of the grid-connected photovoltaics (PV) and energy storage systems under weak grids has been widely researched, the classical improvement methods focus more on suppressing the harmonics introduced by the phase-locked loop (PLL ...

Robust synthesis of feedforward compensators
IEEE Transactions on Automatic Control, 1999 Summary: The design of a feedforward compensator for robust \({\mathcal H}_\infty\) or \({\mathcal H}_2\) performance under structured uncertainty is considered. For linear time-invariant uncertainty, a convex method based on linear matrix inequalities (LMI's) across the frequency variable is given.

Current Harmonic Suppression Algorithm for Asymmetric Dual Three-Phase PMSM
Applied Sciences, 2020 Based on the vector space decomposition (VSD) transformation, the currents of an asymmetric dual three-phase permanent magnet synchronous motor (ADT-PMSM) with isolated neutral points are decoupled into the torque, producing α-ß components in ...

Explicit Reference Governor for Continuous Time Nonlinear Systems Subject to Convex Constraints [PDF]
, 2014 This paper introduces a novel closed-form strategy that dynamically modifies the reference of a pre-compensated nonlinear system to ensure the satisfaction of a set of convex constraints.

Articulating: the neural mechanisms of speech production [PDF]
, 2019 Speech production is a highly complex sensorimotor task involving tightly coordinated processing across large expanses of the cerebral cortex. Historically, the study of the neural underpinnings of speech suffered from the lack of an animal model.

Multislope PI Modeling and Feedforward Compensation for Piezoelectric Beam [PDF]
Mathematical Problems in Engineering, 2020 The hysteresis nonlinearity greatly reduces the tracking precision of piezoceramic actuators for expected displacement in a high-accuracy positioning system. In order to effectively compensate the hysteresis for piezoelectric ceramics, a novel modeling method, namely, multislope PI (Prandtl–Ishlinskii) was proposed.

Journal of Marine Science and Engineering, 2023 Soft manipulators have desirable environmental compatibility because of their pliability. However, this pliability also brings challenges to modeling and control when considering contact or collision with the environment. In previous work, we established
