| description | Gas turbine-driven permanent magnet synchronous generator (PMSG) face complex and uncertain load conditions, which can affect equipment performance and power supply reliability. To enhance system robustness, this paper proposes an adaptive two-degree-of-freedom (2-DOF) H∞ robust voltage control strategy for PMSG distributed generation system. The control structure consists of a two-degree-of-freedom H∞ controller and an adaptive internal model controller. First, an H∞ voltage controller with an H∞ load observer is proposed to suppress non-periodic disturbances. Then, an H∞ voltage feedforward controller is proposed to improve the response capabilities of the voltage command. Closed-loop stability is analyzed, and controller parameters are optimized accordingly. Finally, an adaptive internal model controller is proposed to estimate and suppress periodic load disturbances. The proposed control strategy is validated on a 60 kW turbine-driven PMSG platform. Experimental results demonstrate that the proposed control strategy significantly improves the robustness and reliability of power supply in PMSG generation system. |
