퍼지논리에 의한 XY 테이블의 위치제어기 설계

초록

?One significant error in XY table is due to friction and disturbance. However the characteristics of this friction is not easy to predict and analyze because of its nonlinearity . Therefore, it is difficult for conventional controller to compensate it effectively. In order to solve this problem., this paper presents a position controller based on fuzzy logic controller(FLC) that is suitable for system with unknown and unmodelled dynamics. The performance of the proposed controller are demonstrated by simulation results.
