Abstract

A fuzzy logic controller (FLC) used for seam tracking of arc-welding robot is presented in this paper. The paper discusses the issues of the fuzzy logic which are pertinent to design and implementation of an intelligent seam tracking controller. This controller is designed to operate in the uncertain environment of the weld seam tracking. The characters of the proposed fuzzy controller combined with an integrator have provided for salient feature of robot joint position control under uncertain disturbances. It enables an arc-welding robot to track the weld seam accurately. The effectiveness of the proposed fuzzy algorithms is demonstrated by computer simulations. Compared with conventional PID controller, the fuzzy controller yields conspicuously improved performance.
