Abstract :
In this article, the authors propose a new multivariable method of identifying the flexible structure with piezoelectric actuators based on maximum likelihood algorithm in frequency domain. The algorithm has been successfully applied on a particular H-type flexible structure with four inputs and four outputs on a restricted frequency range.
