Abstract

A deadzone compensator is designed for a XY positioning table using fuzzy logic. The classification property of fuzzy logic systems makes them a natural candidate for the rejection of errors induced by the deadzone, which has regions in which it behaves differently. A tuning algorithm is given for the fuzzy logic parameters, so that the deadzone compensation scheme becomes adaptive, guaranteeing small tracking errors and bounded parameter estimates. Formal nonlinear stability proofs are given to show that the tracking error is small. The fuzzy logic deadzone compensator is implemented on a XY positioning table to show its efficacy.

퍼지논리를 이용한 XY 테이블의 데드존 보상기법을 제안한다. 퍼지논리 함수의 분류특성은 다양한 영역을 가진 데드존에 의해 유발되는 오차를 제거하기 위한 보상기 설계를 가능케 한다. 데드존 보상이 적응적이고 추적오차와 파라미터 추정치가 유계가 되는 퍼지논리 파라미터 동조알고리듬과 안정도 증명을 제시한다. 퍼지논리 데드존 보상기를 위치 테이블에 실험함으로써 데드존의 해로운 영향을 줄이는 효과를 보여준다.
