(54)SYSTEM IDENTIFICATION DEVICE, SYSTEM IDENTIFICATION METHOD, SYSTEM IDENTIFICATION PROGRAM, AND RECORDING MEDIUM RECORDING SYSTEM IDENTIFICATION PROGRAM


(57) A system identification device for performing fast real-time identification for a system from input/output data includes a filter robust to disturbance, by setting the maximum energy gain from the disturbance to a filter error, as an evaluation criterion, smaller than a given upper limit. The filter estimates a state estimation value of a state of the system.
