An FRIT Method for Disturbance Attenuation Using Input-Output Data Generated from Disturbance Responses

Abstract

This paper considers controller parameters tuning method for regulator problems using FRIT method. The FRIT method for regulator problems tunes the control parameters so that the disturbance response follows the reference model output. The paper tries to give a method for estimating disturbances for an FRIT method using input-output data generated by disturbances. The proposed method assumes that the disturbance is an impulse-type signal, but its magnitude is unknown, and estimates the magnitude of the disturbance, while it obtains the control parameters simultaneously. Hence, the proposed method gives an FRIT method for regulator problems by only using one-shot input-output data for unknown impulse-type distrubances. The efficiency of the proposed method can be shown through a numerical example.
