LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)

说明：  此模型中的撬棍不是使用IGBT或理想开关制造的。 通过 改变转子侧变流器的参考电压来模拟撬棍电路的切入和切出 。 该模型是使用MATLAB R2010a创建的。 控制策略是最常见的去耦 算法和MPPT(The crowbar in this model is not manufactured using IGBTs or ideal switches. by The reference voltage of the rotor-side converter is changed to simulate the cut-in and cut-out of the crowbar circuit. The model was created using MATLAB R2010a. Control strategy is the most common decoupling Algorithm and MPPT)
