摘要

多输入/多输出(MIMO)振动测试的交叉光谱规范具有挑战性。本文提出了一种测试方法，其中输出(控制点)自动光谱的规格是可用的。指定了输出的自谱，导出了输出之间的交叉谱，这将最小化输入(驱动信号)的自谱的轨迹，约束输入谱密度矩阵是正定的。假设是大自然喜欢最小能量解。

Minimum Input Trace for Multiple Input Multiple Output Linear Systems

Specification of the cross spectra for a multiple-input/multiple-output (MIMO) vibration test is challenging. This paper presents a method for tests where the specifications of the output (the control points) autospectra are available. The autospectra of the outputs are specified and cross spectra between the outputs are derived that will minimize the trace of the autospectra of the inputs (the drive signals) with the constraint that the input spectral density matrix is positive definite. The hypothesis is that nature likes a minimum energy solution.
