The blade section is a single-celled composite structure with symmetric layup configuration of circumferentially uniform stiffness (CUS), exhibiting displacements of vertical\/lateral bending coupling. Flutter suppression for divergent instability is investigated, with blade driven by nonlinear aerodynamic forces. Theoretical modeling of CUS-based structure is implemented based on Hamilton variational principle of elasticity theory. The discretization of aeroelastic equations is solved by Galerkin method, with blade tip responses demonstrated. The LLI controller is characterized by LTR at the plant input. The effects of LLI controller are achieved and illustrated by displacement responses, controller responses and frequency spectrum analysis, respectively.<\/jats:p>","DOI":"10.1177\/0142331219888415","type":"journal-article","created":{"date-parts":[[2019,12,6]],"date-time":"2019-12-06T02:04:27Z","timestamp":1575597867000},"page":"1255-1270","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Theoretical modeling and vibration control for pre-twisted composite blade based on LLI controller"],"prefix":"10.1177","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1439-4499","authenticated-orcid":false,"given":"Ting-Rui","family":"Liu","sequence":"first","affiliation":[{"name":"College of Mechanical &amp; Electronic Engineering, Shandong University of Science &amp; Technology, China"}]},{"given":"Ai-Ling","family":"Gong","sequence":"additional","affiliation":[{"name":"Business School, Qingdao University of Technology, China"}]}],"member":"179","published-online":{"date-parts":[[2019,12,5]]},"reference":[{"issue":"2","key":"e_1_3_3_2_1","first-page":"196","article-title":"Research and control of blade aeroelastic stability of large horizontal axis wind turbine","volume":"34","author":"Chang L","year":"2018","unstructured":"Chang L, Xu W, Wu H (2018) Research and control of blade aeroelastic stability of large horizontal axis wind turbine.
