To address this, this paper proposes a novel sensorless and PLL\u2010less deadbeat control strategy. Grid voltage is predicted without physical sensors, and PLL is eliminated, thereby enhancing APF stability. Compared to conventional methods, the proposed strategy achieves faster dynamic response, zero steady\u2010state error, and improved harmonic suppression under low\u2010voltage ride\u2010through (LVRT) and load mutation scenarios. Real\u2010time identification of the equivalent inductance L ensures consistency between the control model and actual system dynamics. The deadbeat control is further enhanced to eliminate inherent control delays and achieve instantaneous current tracking with zero steady\u2010state error. Simulation and 1\u2010kVA experimental results demonstrate enhanced harmonic suppression, faster dynamic response, and better adaptability under complex grid conditions, confirming the method's practicality and cost\u2010effectiveness.<\/jats:p>","DOI":"10.1002\/cta.70076","type":"journal-article","created":{"date-parts":[[2025,7,21]],"date-time":"2025-07-21T01:10:26Z","timestamp":1753060226000},"page":"1796-1814","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A PLL\u2010Less Grid Voltage Sensorless Improved Deadbeat Control for APF With LVRT Capability"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-0798-9417","authenticated-orcid":false,"given":"Jianling","family":"Liao","sequence":"first","affiliation":[{"name":"School of Mechanical and Electrical Engineering China University of Mining and Technology  Beijing China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4770-4855","authenticated-orcid":false,"given":"Wei","family":"Yuan","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering China University of Mining and Technology  Beijing China"}]},{"given":"Zhenshuo","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering China University of Mining and Technology  Beijing China"}]},{"given":"Shunyou","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering China University of Mining and Technology  Beijing China"}]},{"given":"Xu","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering China University of Mining and Technology  Beijing China"}]},{"given":"Jia","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Mechanical and Electrical Engineering China University of Mining and Technology  Beijing China"}]}],"member":"311","published-online":{"date-parts":[[2025,7,20]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/JESTPE.2023.3329171"},{"issue":"7","key":"e_1_2_9_3_1","first-page":"6989","article-title":"A Paralleled Current and Voltage Control Strategy With Compound PI Controllers for Three\u2010Phase Active Power Filters","volume":"39","author":"Yan Q.","year":"2023","journal-title":"IEEE Transactions on Power Electronics"},{"key":"e_1_2_9_4_1","doi-asserted-by":"crossref","unstructured":"M.Ou J.Zou Q.Liu andH.Yang \u201cA Dual\u2010Loop Control Strategy Based on PI and Repetitive Control for APF With CoolSiC\u2122 MOSFET \u201d inProc.
