XY 테이블의 신경망제어

국문 초록 (Abstract)

신경회로망을 이용한 XY 테이블의 비선형 보상기법을 제안한다. 제안된 신경망 제어기는 시스템의 비선형 성분에 의한 성능저하를 보상하는 신경회로망과 시스템의 안정화를 위한 비례미분(PD) 제어기로 구성된다. 신경망 보상 구조가 적응적이고 추적오차와 파라미터 추정치가 유계가 되는 신경망 파라미터 동조알고리듬과 안정도 증명을 제시한다. 신경망 제어기를 위치 테이블에 실험함으로써 비선형 성분에 의한 성능저하를 줄이는 효과를 보여준다.

This paper presents control designs using neural networks (NN) for a XY positioning table. The proposed neuro-controller is composed of an outer PD tracking loop for stabilization of the fast flexible-mode dynamics and an NN inner loop used to compensate for the system nonlinearities. A tuning algorithm is given for the NN weights, so that the NN compensation scheme becomes adaptive, guaranteeing small tracking errors and bounded weight estimates. Formal nonlinear stability proofs are given to show that the tracking error is small. The proposed neuro-controller is implemented and tested on an IBM PC-based XY positioning table, and is applicable to many precision XY tables. The algorithm, simulation, and experimental results are described. The experimental results are shown to be superior to those of conventional control.
