In order to further enhance the comprehensive performance of the actuator and improve its adaptability to extreme working conditions, a multi-objective hierarchical optimization strategy was proposed based on the NSGA-II algorithm by analyzing its structural principle, magnetic circuit characteristics and electromagnetic force characteristics. The moving coil actuator, as the main driving component, and the moving iron actuator, as the auxiliary driving component, are selected as the first- and second-layer optimization objects for multi-objective optimization design. Results indicate that the actuator achieves starting forces of 587.6[Formula: see text]N and 191.4[Formula: see text]N under cooperative drive mode and separate drive mode, respectively. Following optimization, these forces increased by approximately 2.2% and 22.4%, while the mover mass was reduced by about 7.2%. The actuator\u2019s thrust density, response speed, and structural compactness were effectively enhanced. The proposed approach can be used to solve the complex multi-objective optimization tasks in ELA designing.<\/jats:p>","DOI":"10.1142\/s0218001426560045","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T07:22:17Z","timestamp":1770880937000},"source":"Crossref","is-referenced-by-count":0,"title":["Multi-Objective Hierarchical Optimization Design of Compound Electromagnetic Linear Actuator"],"prefix":"10.1142","volume":"40","author":[{"given":"Shanzhen","family":"Xu","sequence":"first","affiliation":[{"name":"Faculty of Transportation Engineering, Huaiyin Institute of Technology, Huai\u2019an 223003, P.
