N2 - This work deals with the identification of MDOF non-linear systems with a convergent Volterra series representation. These kind of nonlinear systems are commonly identified in the frequency domain from their Higher-order Frequency-Response-Functions (HFRFs). This process requires multi-dimensional Fourier transforms, which are cumbersome and computationally expensive and prevent more widespread usage. To avoid the multi-dimensional Fourier transformations, in previous work on SISO systems the equation have been projected into linear subsystems and then modelled by Associated Linear Equations (ALEs). This method identifies an Associated Frequency-Response- Function (AFRF) for ALE, which requires only an unidimenstional Fourier transformation. This paper exposes the mathematical basis for the extension of the ALE concept from SISO to MDOF systems.
