要約(英語): In this paper, a novel synthesis method of disturbance observer which can asymptotically estimate a biased sinusoidal disturbance using the conventional disturbance observer is studied. The basic idea is to synthesize the disturbance observer gain matrix based on the following two considerations: 1) a zero located at the origin can be assigned to the closed-loop transfer function Gdd(s) from the disturbance to the disturbance estimation error, 2) all poles of Gdd(s) can be obtained in the complex left half-plane. The zero assignment of Gdd(s) can be accomplished using only one element of the gain matrix, and all poles of Gdd(s) can be assigned using the remaining elements of the gain matrix. The usefulness of the proposed method is verified by the angle control of a direct current(DC) motor system with the estimation performance of disturbances.
