PURPOSE: To make it possible to measure the open-loop characteristics of a multiple input and multiple output dynamic system by using the measured result of a closed-loop system. CONSTITUTION: A difference module 43 generates a difference signal E=R-Z between a system input signal R and an estimation signal Z. Then, a control module 45 receives the signal E as an input signal, and outputs and sends an intermediate signal U=CE in response to the reception of the E. Then, a plant module 47 receives the signal U, and sends a system output signal Y=PU in response to the reception of the U. A module 49 is disposed in a feedback route to the module 43, receives the output Y as the input signal, and outputs the signal Z=HY in response to the reception of the Y. In this case, C, P and H are matrixes having sizes n3×n1, n2×n3 and n1×n2, where n1, n2 and n3 are selected positive integers. |
