A paper entitled “Sparse stability diagrams of LSCF method via strategic pole destabilization using orthogonal matching pursuit” has been published in Mechanical Systems and Signal Processing. The paper is based on a Master’s thesis work of a former lab member Shogo Shimada. The paper proposes a novel methodology to remove spurious modes in the stability diagrams of the least squares complex frequency domain method (LSCF) for experimental modal analysis.
