전역적 안정성을 보장하는 비선형 외란 관측기 설계 및 강인 안정도 조건

A nonlinear version of disturbance observer is presented. The system under consideration is an uncertain single input single output nonlinear system and the nominal plant is also a nonlinear system. Compared to the previous implementation given in [8], the proposed scheme does not require an auxiliary variable anymore, thus it has a simpler and more intuitive structure. A robust stability condition for the overall closed-loop system is also provided.

This paper presents a robust control design method for uncertain linear systems in normal form using state feedback based disturbance observer where the uncertain linear system has not only parameter uncertainties but also bounded external disturbances. For this uncertain system, it is presented how to design a disturbance observer when the state variable is measurable. Then, it is shown that the designed disturbance observer (DOB) based control can practically stabilizes the uncertain system. The simulation results show that the proposed DOB based control successfully stabilizes an uncertain system.
