Based on the analysis of the mechanism of wire tension control by using torque motors in the multi-wire saw machining process,some mathematical models of a tension control system are studied,and an adaptive algorithm is designed for controlling the wire tension.In this algorithm of tension control,the rotation speeds and waving angle of motors are measured and fed back to the controller,and the NLMS(normalized least mean squares) algorithm is used to calculate the adaptive correction value and control the wire tension accurately.The computer simulation results in Matlab software validate the high accuracy for controlling the system of the wire tension with the NLMS algorithm in the multi-wire saw machining process.
