A Generalized Supertwisting Algorithm

open access: yesIEEE Transactions on Cybernetics, 2023
The work proposes a generalized supertwisting algorithm (GSTA) and its constructive design strategy. In contrast with the conventional STA, the most remarkable characteristic of the proposed method is that the discontinuous term in the conventional STA is replaced with a fractional power term, which can fundamentally improve the performance of the ...

Abnormal Data Detection Method Based on Ant Colony Algorithm [PDF]

open access: yesJisuanji gongcheng, 2016
Since the traditional outlier detection technology based on Omeasure needs to search all paths while detecting abnormal data and it is easy to make misjudgments under the scenario of less amount of data.Hence,it has obvious defects on the efficiency and
