Adaptive Fuzzy Super-Twisting Sliding Mode Control for Microgyroscope
Published 2019-01-01“…Firstly, an adaptive algorithm is used to estimate the unknown parameters and angular velocity of microgyroscopes. Secondly, in order to improve the performance of the system and the superiority of the super-twisting algorithm, this paper utilizes the universal approximation characteristic of the fuzzy system to approach the gain of the super-twisting sliding mode controller and identify the gain of the controller online, realizing the adaptive adjustment of the controller parameters. …”

Hunting for Cold Exoplanets via Microlensing
Published 2023-08-01“…Although the number of detected planets is relatively modest ($\sim $130 planets to date) compared to that discovered by radial velocity and transit methods, microlensing probes a part of the parameter space (host separation as a function of planet mass), which is mostly not accessible in the medium term to any other technique. …”

Ionospheric Response to the Extreme 2024 Mother's Day Geomagnetic Storm Over the Latin American Sector
Published 2024-12-01“…CHPI also features a Fabry‐Pérot interferometer (FPI) and an All‐Sky Imager (ASI). Super EPB was observed in the American sector. This structure drifted westward at a velocity of ∼140 m/s and had a large latitudinal extension, reaching about 36° geomagnetic latitude, this corresponds to an apex height of around 4,500 km. …”
