초록
The purpose of this paper is to improve tracking performance for an EMS system using variable structure control. To improve current control of characteristics and to reduce chattering, a reaching law is applied. A disturbance observer using sliding observer is designed to compensate the influence of disturbances. This observer compensates modelling uncertainty and steady state error as well as external disturbance. The effectiveness of the proposed control scheme is demonstrated by experiments
