Abstract

Fuzzy control of thrust force in drilling of composite ma terials is studied in this paper. A new hybrid fuzzy learn ing/gain adaptive control scheme is proposed. In this ap proach, the on-line gain adaptation and fuzzy learning con trol are coordinated together to ensure a superior control performance of the trained fuzzy controller under large pro cess gain variations. This method makes fuzzy learning control practical for complex and time-varying processes such as drilling of composite materials. Simulations are conducted to evaluate the fuzzy controllers.
