Frequency domain method , however , takes an advantage in the aspect 而以传递函数矩阵为基础的频域法在这方面具有很大的优势。
Transfer function matrix 传递函数矩阵
A method to identify the damping parameters of machine joint surface is proposed based on the tested frequency response functions 提出一种基于实测传递函数矩阵来识别机械结合面阻尼参数的新方法。
We analyzed its nature of resolving coherent sources and compared the influence of different focusing matrices . simulations are conducted to test the performance of these focusing matrices . 4 分析了cssm方法分辨相干源的实质,即通过频域平均消除了相关函数矩阵的奇异性;分析比较了几种不同聚焦矩阵对算法性能的影响。
In part two , the focus is on the stabilizability and detectablity of 2 - d singular systems . necessary and sufficient conditions for stabilizability and detectablity of 2 - d singular systems are obtained respectively , and the relationship between bibo stability and internal stability is discussed based on this conditions . the observer design procedures are also provided 在能稳性和能检测性部分,用频域研究方法,分别给出了2 - d奇异系统能稳、能检测的两个等价条件,一个是能稳、能检测的秩判别条件,另一个为bezout恒等式存在稳定的有理函数矩阵解。
