Abstract: To change the traditional control system of dyeing wind machine from DC motor driving and autotransformer to a new model by AC motor driving VVVF and Single-Chip computer controller (SCCC) was described. By theoretical analysis to regulated object, a new control tactics and controller by take Single-Chip computer as core were obtained and developed. Under the condition of no any analog transducer such as velocity and tension, the dyeing fabric in the control system can be controlled by permanent velocity and tension automatically in order to stabilize and increase the dyeing quality o fabric. The more than two years application of control system shows obvious reliability and save on power energy.
