加权l1-极小恢复k块稀疏信号恢复，加的权重是多个，并且不相等。(Sparse signals recovered by the weighted l1-minination.)

说明：  采用通用动态尾流理论进行风力机气动力学的计算分析,并用 MATLAB/Simulink进行编 程,建立了风力机传动链的数学模型。 在 MATLAB/Simulink中进行传动链系统的编程运算,建立了 风力机 ADAMS柔性多体结构动力学仿真模型,并利用 MATLAB/Simulink和 ADAMS进行风力机振 动性能的联合仿真。 仿真时将气动载荷加载到风力机叶片结构上,将传动系统模型的反扭矩加到 AD AMS风轮模型上,同时考虑风力机的结构变形对气动性能、传动性能产生的影响。 仿真最终实现了风 力机系统振动性能耦合分析,其数据同实验测试数据比较表明,该联合仿真方法可以较好地模拟风力机 的振动特性。(TheaerodynamicscharacteristicsofwindturbinewerecalculatedbyapplyingGDWthe oryandwereprogrammedin MATLAB/Simulink.
