摘　　要： 为解决风电叶片螺栓套疲劳试验过程中实际载荷与期望载荷的跟随控制问题,设计一种风电叶片螺栓套疲劳试验机并对期望载荷与实际载荷间的跟随控制策略进行研究。采用基于最小均方(LMS)的谐波消除和幅值控制策略,通过LMS算法的权值调整机制,解决实际载荷的量测噪声和幅值衰减现象。通过Matlab/Simulink,建立试验机模型,对算法的有效性进行验证;搭建试验机平台,通过现场疲劳试验对跟随效果进行研究。结果表明,在基于LMS的跟随控制策略下,螺栓套期望载荷与实际载荷的跟随效果良好,载荷误差不超过±5 k N,为风电叶片螺栓套疲劳特性的研究与应用提供可能。 To solve the tracking control problem between the actual load and the expected load during the fatigue test of bolt sleeve for wind turbine blade, a kind of fatigue testing machine of bolt sleeve for wind turbine blade was designed and the tracking control strategy between the expected load and the actual load was studied. The harmonic elimination and amplitude control strategy based on least mean square and amplitude attenuation phenomena for the actual load （LMS） through algorithm was used to solve the measurement noise the weight adjustment mechanism of LMS algorithm. The model of the testing machine was established through the Matlab/Simulink, and the algorithmic validity was verified; the platform of testing machine was set up to research tracking effect through field fatigue testing. The results show that the tracking effect of expected load and actual load of bolt sleeve based on the tracking control strategy of LMS is fine, the load error is less than ±5kN, and provide possibility for research and application of fatigue characteristics of bolt sleeve for wind turbine blade.
