查询词典 null

A method based on the orthogonal property between signal subspace and noise subspace is proposed for robust adaptive beamforming. The robustness would be achieved by projecting the signal steering vector and the null constrain steering vector on signal subspace followed by LCMVB.

针对此情况，基于信号子空间与噪声子空间的彼此正交特性，对存在误差的信号导向矢量和干扰导向矢量，同时向信号于空间投影，然后对投影后的导向约束采用LCMV准则进行自适应波束形成。

An input phase voltage is divided into a main range and a transition range in which new P, M, N conditions and PM, NP, MN transition conditions are defined, some null vector is selected and the condition combination sequence of bidirectional power switches are adjusted in each modulation period to realize the safe, reliable and rapid commutation and the stable operation of the matrix converter.

本发明属于矩阵变换器控制技术，为一种用于矩阵变换器的控制方法，通过把输入相电压划分为主区间和过渡区间、在过渡区间定义新的P、M、N状态和PM、NP、MN暂态以及在每个调制周期内选择特定的零矢量并调整双向功率开关状态组合顺序，实现矩阵变换器安全、可靠、快速换流和稳定运行。
