Constraint Satisfaction in Current Control of a Five-Phase Drive with Locally Tuned Predictive Controllers [PDF]

, 2019
The problem of control of stator currents in multi-phase induction machines has recently been tackled by direct digital model predictive control. Although these predictive controllers can directly incorporate constraints, most reported applications ...

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

An Improved Grid Voltage Feedforward Strategy for High-Power Three-Phase Grid-Connected Inverters based on the Simplified Repetitive Predictor [PDF]

, 2016
When faced with distorted grid voltage, more harmonics will appear in the output currents of the gridconnected inverters. The grid voltage feedforward strategy, as the most direct solution to compensate the harmonics, however, is seriously affected by ...

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles
