要約(日本語): In the field of process control and mechanical control, the one-degree-of-freedom(1DOF) control system is widely adopted. But we can not always get an ideal output just by using the 1DOF control system, in many cases that the uncertainty of modeling and disturbance of the control system are intervening in it. So, this paper aims to propose a new disturbance observer law under the generalized minimum variance criterion, to obtain the estimated disturbance value for compensating for the effect of disturbance and minimize the variance of the input value of the controlled plant. Moreover, this paper builds a 2DOF control system by Generalized Minimum Variance Disturbance OBserver(GMV-DOB) and Generalized Minimum Variance Controller(GMVC), for verifying the proposed disturbance observer.
