A discrete-time model of the three-phase PWM rectifier is established using the forward Euler discretization method, and a dual-loop discrete-time feedback linearization control (DDFLC) is given. Based on the DDFLC, the DDAC is designed. Firstly, an adaptive inductance disturbance observer (AIDO) based on the gradient descent method is proposed in the current control loop. The AIDO is used to estimate lump disturbances caused by mismatched inductance parameters and then compensate for these disturbances in the current controller, ensuring its strong robustness to inductance parameters. Secondly, a load parameter adaptive law (LPAL) based on the discrete-time Lyapunov theory is proposed for the voltage control loop. The LPAL estimates the DC load parameter in real time and subsequently adjusts it in the voltage controller, achieving DC load adaptability. Finally, simulation and experimental results show that the DDAC exhibits better steady and dynamic performances, less current harmonic content than the DDFLC and the dual-loop discrete-time PI control (DDPIC), and a stronger robustness to inductance parameters and DC load disturbances.<\/jats:p>","DOI":"10.3390\/s24103010","type":"journal-article","created":{"date-parts":[[2024,5,9]],"date-time":"2024-05-09T10:31:16Z","timestamp":1715250676000},"page":"3010","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Discrete-Time Adaptive Control for Three-Phase PWM Rectifier"],"prefix":"10.3390","volume":"24","author":[{"given":"Bo","family":"Hou","sequence":"first","affiliation":[{"name":"School of Electrical Engineering, Shaanxi University of Technology, Hanzhong 723001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayan","family":"Qi","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering, Shaanxi University of Technology, Hanzhong 723001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huan","family":"Li","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering, Shaanxi University of Technology, Hanzhong 723001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"166502","DOI":"10.1109\/ACCESS.2021.3135083","article-title":"A Review on Microgrids\u2019 Challenges & Perspectives","volume":"9","author":"Saeed","year":"2021","journal-title":"IEEE Access"},{"key":"ref_2","first-page":"3044","article-title":"Finite-Time Adaptive Fuzzy Control for Three-Phase PWM Rectifiers With Improved Output Performance","volume":"70","author":"Fu","year":"2023","journal-title":"IEEE Trans.
