By constructing an intermediate variable observer to obtain accurate system states and reconstruct attack signals, based on which a non-singular terminal sliding mode control strategy is proposed to eliminate the effects of false data injection attack on the system. This strategy increases the convergence speed and transient response of the system in comparison with existing results. Furthermore, a continuous switching term is designed to suppress controller chattering. Parameters of the intermediate variable observer are determined by solving linear matrix inequality. The proposed method is applied to an electric amplidyne system for verifying its superiority.<\/jats:p>","DOI":"10.1177\/09596518241302480","type":"journal-article","created":{"date-parts":[[2025,1,6]],"date-time":"2025-01-06T07:32:12Z","timestamp":1736148732000},"page":"1132-1142","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Sliding
