Adaptive inverse control of speed synchronization system for a multi-wire saw
多线切割机速度同步系统的自适应逆控制

This paper analyzes the mechanical structure-principle of the speed and tension control for the tension hamper in a multi-wire saw. To improve the existing control performance of the PID controller, we propose an adaptive inverse control algorithm which takes the main motor as the reference model and consists of a system identification process and an adaptive controller process. When the multi-wire saw is in operation, the controller adaptively adjusts the speed of the supplying motor to track the output speed of the main motor. The experiment results validate the system feasibility. Analysis of the tracking error is given in-depth, and the measures for its reduction are also proposed.
