Study of draw texturing machine's control system based on PLC

Presented a design for the draw texturing machines control system according to the current domestic situation of draw texturing machines and relied on the all kinds of foreign draw texturing machines control systems.The design had friend human computer interfaces to monitor the field situation,realized the high precision temperature control with the PID Fuzzy control method,realized the high precision control for motor combining PLC with closed loop control and tension monitor on line of variable frequency drives,avoid the hard border and overlapping yarn by four grades stroke modification and changing winding angle incessantly.
