Experimental phase control of a 100 laser beam array with quasi-reinforcement learning of a neural network in an error reduction loop. [PDF]
Optics Express, 2020 An innovative scheme is proposed for the dynamic phase control of a laser beam array. It is based on a simple neural network included in a phase correction loop that predicts the complex field array from the intensity of the induced scattered pattern ...

Phase-Controlled Thyristor Sub-Synchronous Damper Converter for a Liquefied Natural Gas Plant
Energies, 2021 In electrified liquefied natural gas (LNG) plants variable frequency drives (VFDs) interact with turbine-generator (TG) units creating torsional vibrations known as sub-synchronous torsional interactions (SSTIs). Torsional vibrations can be dangerous for

Self-Reproducing Hidden Attractors in Fractional-Order Chaotic Systems Using Affine Transformations
IEEE Open Journal of Circuits and Systems, 2020 This article proposes a unified approach for hidden attractors control in fractional-order chaotic systems. Hidden attractors have small basins of attractions and are very sensitive to initial conditions and parameters.

Frequency-Selective Beamforming Array Antenna Systems with Frequency-Dependent Phase Shifters [PDF]
Journal of Electromagnetic Engineering and Science, 2019 A frequency-selective beamforming array antenna system is proposed for next-generation mobile applications. Whereas a conventional phased array steers antenna beams in the same direction, the proposed system involves a channel-selective beam for each ...
