【摘要】 变距系统是风力发电机组实现变距控制和安全刹车的关键机构,本文基于H_∞控制理论讨论了变距系统的H_∞控制方案。本文所提出的控制方案既保证了系统的稳定性和快速跟随性能,又抑制了系统模型摄动及外部扰动对系统的影响,保证了系统的鲁棒性。仿真结果也验证了本文所提方案是行之有效的。更多还原

【Abstract】 Active control of a horizontal axis wind turbine via pitching of the rotor blades is considered in this paper. It presents a robust control design for a variable-speed adjustable-pitch wind energy conversion system with an uncertain model. A H∞ controller is designed to drive the turbine speed to extract invariable power from the wind and to allow pitch adjustment to power regulation. It is the purpose of this paper to test and validate a H∞ controller for a wind turbine by simulation.更多还原
