摘　　要：采用H∞混合灵敏度鲁棒控制原理,开发了风力机的转速控制器,提高了风力发电系统转速控制的抗干扰性,从而获得最大能量追踪的快速性和稳定性,使得风力发电系统能够捕获更多的风能,并最终提高风力发电的效率。在实验室开发了基于直流电力总线的风力发电实验系统,最后给出了控制器的仿真和实验的数据结果,验证了控制器的有效性。Mixed sensitivity approach of H∞ robust control was used to develop the rotating speed controller of wind turbine. The robustness of speed controller was improved, while a fast and stable maximum power point tracking was achieved, which made the generation system capture more wind energy, and finally got the high generation efficiency. An experimental mode of wind generation unit based on DC system was developed in the laboratory. The simulation and experimental results were given to confirm the validity of the proposed controller.
