Abstract

A new robust disturbance observer was proposed in the article in order to estimate the modelling uncertainty and external disturbances. Based on the design of the nonlinear disturbance observer, in order to enhance its robustness, the observer is improved by the application of the principle of sliding mode. Then the proof on the stability of the observer and the principle of the parameter design are given. The simulation results reveal that the proposed method has higher estimation precision, speed, and stronger robustness compared with the above two kinds of observer.
