This paper addresses the development of a nonlinear model based interval model control system for the quasi-keyhole arc welding process, a novel arc welding process which has advantages over the laser welding process and conventional arc welding processes. The structure of the nonlinear model chosen was proposed based on an analysis of the quasi-keyhole(More)
—A split-band directly modulated fiber optical CATV system employing −1 side-mode injection-locked and semiconductor optical amplifier (SOA)-based optical single sideband (SSB) modulation techniques is proposed and experimentally demonstrated. For our proposed systems, it is relatively simple to implement as only one SOA is required. Excellent performances(More)
