等価入力外乱推定による外乱除去性能の向上

抄録

This paper presents a new method of improving the disturbance rejection performance of a servo system by estimating an equivalent input disturbance. First, the concept of equivalent input disturbance is defined. Next, the configuration of an improved servo system employing the new disturbance estimation method is described. Then, a method of designing a control law employing the disturbance estimate is explained. Finally, the positioning control of a two-finger robot hand is used to demonstrate the validity of the method.
