20.500.12556/DKUM-96496 Controllability and small-signal oscillations of magnetic flux linkages in doubly fed induction machines This paper examines the controllability of the stator and rotor magnetic flux linkages of doubly fed induction machines (DFIMs), considering small-signal oscillations and their relationship with electromagnetic machine design. To this aim, we first analyze 66 sets of lumped parameters from the dynamic model of a DFIM. Based on this, we classify DFIMs into three categories based on their modal parameters, namely, two for wind applications and one for pumped-hydro applications. Additionally, we identify reciprocal relationships between the damping of both identified oscillatory modes and the largest eigenvalues of the stator and rotor controllability Gramian matrices. Among the different lumped parameters, the winding resistances are found to influence these relationships the most. All analyzed DFIMs for wind applications were found to be less controllable and to exhibit better damping of oscillatory modes than DFIMs for pumped-hydro applications. Furthermore, based on the results of the controllability analysis, we selected three objective function candidates suitable for an optimization procedure aimed at minimizing the energy required to control the rotor flux linkages. An example objective function was evaluated in a multi-objective DFIM design process for wind applications that enables the design of more controllable machines that provide the desired damping of oscillations, which can consequently contribute to improving grid resilience. contorollability design optimization doubly fied indusction generators modal analysis obvladljivost dvojno napajani indukcijski generatorji modalna analiza optimozacija oblikovanja true false true IEEE XPLORE Angleški jezik Slovenski jezik https://ieeexplore.ieee.org/xpl/RecentIssue.jsp?punumber=60 Članek v reviji 2026-01-14 14:04:31 2026-01-14 14:04:32 2026-05-28 03:08:51 0000-00-00 00:00:00 2025 0 0 str. 1325-1336 issue 2 Vol. 41 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-12-24 621.313 263434499 10.1109/TEC.2025.3647982 1558-0059 Controllability_and_Small-Signal_Oscillations_of_Magnetic_Flux_Linkages_in_Doubly_Fed_Induction_Machines_(1).pdf Controllability_and_Small-Signal_Oscillations_of_Magnetic_Flux_Linkages_in_Doubly_Fed_Induction_Machines_(1).pdf 1 2E209563758EA4D75E6108B076BE273F 2e935ea176213b3f8a3f5e3edd44a40390c89d8a0b076ef22df63efa097f66ec 3fb78970-59d4-11f1-8108-00155d580e34 https://dk.um.si/Dokument.php?lang=slv&id=206468 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
