PROBLEM TO BE SOLVED: To conduct a precise vibration test even if a machine is a multi-axial vibration-testing machine. SOLUTION: The vibration-testing machine control system (100) is provided with a mounting stand (12), excitation means (11x and 11z), detection means (13x and 13z), and a control means (2). The control means (2) is provided with a correction means (2) which multiplies an m line (m is a natural number, n≥m) of inner transmission matrix (X) comprising n-dimensional square matrix by an m column of object matrix (R) comprising n-dimensional square matrix for identifying the system to obtain output matrix (O) for each excitation direction, drives the excitation means (11x and 11z) based on the output matrix (O), calculates error matrix (E) by dividing the obtained input matrix (I) by the object matrix (R), calculates correction matrix (C) to correct the inner transmission matrix (X) by calculating the inverse matrix of the error matrix (E), and corrects the inner transmission matrix (X) using the correction matrix (C).
