First, a novel time\u2010varying gain disturbance observer (TVGDO) is developed to estimate the uncertainties. Then, by using the output of TVGDO to modify sliding mode control (SMC), a new TVGDO\u2010based SMC scheme is developed. Although the observation and control precision of conventional fixed gain disturbance observer\u2010based control (FGDOC) for chaotic systems can be guaranteed by a high observer gain, the undesirable spike problem may be caused by the high gain if the initial values of estimate and true states are not equal. The most attractive feature of this work is that the newly proposed TVGDO can eliminate the spike problem by developing a time\u2010varying gain scheme. Finally, the effectiveness of the proposed method is demonstrated by the numerical simulation.<\/jats:p>","DOI":"10.1155\/2021\/8845553","type":"journal-article","created":{"date-parts":[[2021,4,21]],"date-time":"2021-04-21T21:21:37Z","timestamp":1619040097000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Robust
