This challenge motivates the development of algorithms with strong disturbance suppression capability. To address this issue, a continuous-form double-integration-enhanced recurrent neural network (CF-DIE-RNN) algorithm incorporating a novel double-integration-enhanced design concept is first developed to improve robustness against time-varying disturbances. For digital hardware applications, a discrete-form double-integration-enhanced RNN (DF-DIE-RNN) algorithm is then constructed by discretizing the CF-DIE-RNN algorithm using a general four-step discretization formula and a one-step forward difference formula based on Taylor expansion. Rigorous theoretical analysis establishes the convergence properties of the proposed algorithm and characterizes its steady-state residual bounds under different disturbance types, revealing its capability to suppress discrete quadratic time-varying disturbances. Numerical and simulation experiments demonstrate that the DF-DIE-RNN algorithm achieves superior disturbance suppression and more accurate trajectory tracking than existing discrete-form RNN algorithms, confirming its effectiveness for discrete-form Stewart platform control.<\/jats:p>","DOI":"10.3390\/informatics13040049","type":"journal-article","created":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T12:05:49Z","timestamp":1775563549000},"page":"49","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Discrete-Form Double-Integration-Enhanced Recurrent Neural Network for Stewart Platform Control with Time-Varying Disturbance Suppression"],"prefix":"10.3390","volume":"13","author":[{"given":"Yueyang","family":"Ma","sequence":"first","affiliation":[{"name":"College of Information and Artificial Intelligence, Yangzhou University, Yangzhou 225127, China"},{"name":"Jiangsu Province Engineering Research Center of Knowledge Management and Intelligent Service, Yangzhou University, Yangzhou 225127, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3014-7858","authenticated-orcid":false,"given":"Yang","family":"Shi","sequence":"additional","affiliation":[{"name":"College of Information and Artificial Intelligence, Yangzhou University, Yangzhou 225127, China"},{"name":"Jiangsu Province Engineering Research Center of Knowledge Management and Intelligent Service, Yangzhou University, Yangzhou 225127, China"},{"name":"School of Physics and Information Engineering, Guangxi Science & Technology Normal University, Laibin 546199, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1448-3691","authenticated-orcid":false,"given":"Chao","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Information and Artificial Intelligence, Yangzhou University, Yangzhou 225127, China"},{"name":"Jiangsu Province Engineering Research Center of Knowledge Management and Intelligent Service, Yangzhou University, Yangzhou 225127, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"13968","DOI":"10.1109\/JSEN.2024.3376415","article-title":"Miniature six-axis force\/torque sensor based on a Stewart platform and FBG sensing for endoscopic surgery","volume":"24","author":"Li","year":"2024","journal-title":"IEEE Sens.
