Fuzzy variable gain robust control of active magnetic bearings rigid rotor system
IET Electric Power Applications, Volume 18, Issue 1, Page 90-106, January 2024.First, the T‐S fuzzy model of four‐degree‐of‐freedom (4‐DOF) AMBs was established based on the 4‐DOF AMBs rigid rotor equivalent coupling model optimised by the μ‐gap metric. Then, the non‐dominated sorting genetic algorithm II (NSGA‐II) was used to find the relative optimal weight function value of H‐infinity robust controller when AMBs system was at ...
