Modelling and adaptive control of the wire transport system in wire electrical discharge machining

Abstract: Accurate control of the tension of a wire electrode is a requirement of a machine for wire electrical discharge machining. In this paper, a closed-loop wire feed and wire tension control system is presented to guarantee smooth wire transport and a constant tension value. The dynamic model and system identification of the wire transport system is derived to analyse and design the control system. A one-step-ahead adaptive controller is proposed to investigate the dynamic performance of the closed-loop wire tensi… Show more

“…Tran and Choi [8][9][10] proposed an improved mathematical model for roll-to-roll system in printing industry and designed tension controller using backstepping method to realize precise tension control of paper. Yan [11] presented a one-step-ahead adaptive controller to guarantee smooth wire transport and a constant tension value for wire electrical discharge machining. In general, in a multispan roll-to-roll system, a plurality of actuators and senor signals are provided in the tension control to handle tension disturbances between different spans, in particular the moment or speed of the end roller being controlled and measured.…”
