Optimal sensor location for detecting changes in dynamical behavior

We address the problem of optimal sensor location for monitoring the eigenstructure of a multivariable dynamical system. The criterions which are optimized are the power of new tests designed for detecting and diagnosing changes in the eigencharacteristics of a system |3| |12|. The key points are the choice of the parametrization for computing the criterion and the comparison of designs with different number of sensors. The discussion of the numerical results for sensor location includes the analysis of the effect of the geometry of the unknown excitation.
