Sliding mode corrector for jet UAV control (2023)
Journal Article
Wang, X. (2024). Sliding mode corrector for jet UAV control. Aeronautical Journal, 128(1319), 37-72. https://doi.org/10.1017/aer.2023.29

A sliding mode corrector is presented for disturbance rejection in position sensing using relatively accurate velocity measurement. The corrector design is based on a robust second-order sliding mode (2-sliding mode), which makes the fusion of positi... Read More about Sliding mode corrector for jet UAV control.

Signal corrector and decoupling estimations for UAV control (2022)
Journal Article
Wang, X. (2022). Signal corrector and decoupling estimations for UAV control. Aeronautical Journal, 127(1311), 796-817. https://doi.org/10.1017/aer.2022.86

For a class of uncertain systems with large-error sensing, the low-order stable signal corrector and observer are presented for signal correction and uncertainty estimation according to completely decoupling estimation. The model-free signal correcto... Read More about Signal corrector and decoupling estimations for UAV control.

Whole-Genome Resequencing of Worldwide Wild and Domestic Sheep Elucidates Genetic Diversity, Introgression, and Agronomically Important Loci (2021)
Journal Article
Lv, F., Cao, Y., Liu, G., Luo, L., Lu, R., Liu, M., …Li, M. (2022). Whole-Genome Resequencing of Worldwide Wild and Domestic Sheep Elucidates Genetic Diversity, Introgression, and Agronomically Important Loci. Molecular Biology and Evolution, 39(2), Article msab353. https://doi.org/10.1093/molbev/msab353

Domestic sheep and their wild relatives harbor substantial genetic variants that can form the backbone of molecular breeding, but their genome landscapes remain understudied. Here, we present a comprehensive genome resource for wild ovine species, la...

Design and analysis of stable differentiator-predictor (2020)
Journal Article
Wang, X. (2022). Design and analysis of stable differentiator-predictor. International Journal of Control, 95(5), 1228-1250. https://doi.org/10.1080/00207179.2020.1847326

In this paper, the phase lead by the general phase-lead compensator is analysed, and a criterion of its parameters selection is proposed. In order to get the relatively large time-interval prediction for stochastic signal, two types of differentiator... Read More about Design and analysis of stable differentiator-predictor.

Extended signal-correction observer and application to aircraft navigation (2019)
