Choi, YJ Yang, KJ Chung, WK Kim, HR Suh, IH 2024-01-21T09:32:05Z 2024-01-21T09:32:05Z 2021-09-01 2003-02 0018-9286 https://pubs.kist.re.kr/handle/201004/138881 The disturbance observer (DOB) has been widely utilized for high-precision and high-speed motion control applications. In this note, we suggest the robustness measure of the DOB as a criterion to design the robust DOB systems. Also, we suggest its design guidelines especially for second-order systems. Experimental results for an optical disk drive system show the validity of design guidelines.
