英文摘要 |
This paper is concerned with the robust H-infinity control for the direct-drive permanent-magnet synchronous generator(PMSG) with varying stator-parameters. The model with varying current-parameters is considered the uncertain descriptor system, to which we propose an output-feedback H-infinity control scheme, and use the internal-model-principle to develop a type-2 controller for eliminating the impact from the aerodynamic disturbances to the rotational speed in the steady state. The controller synthesis is formulated in solving a set of linear matrix inequalities(LMIs). Simulation results show that the proposed algorithm implements desirable static and dynamic performances, evident disturbance rejection and strong robustness under a wide range of variation in the stator parameters. |
