將卷染機的控制系統從直流電機拖動、自耦調壓器有級調速改造為交流電機拖動和變頻器無級調速。通過對調節對象的理論分析，得到了一種新的控制策略，研制出以單片機為核心的控制器，在不使用速度和張力傳感器的條件下，控制系統可自動對被染織物進行恒速與恒張力控制，以利于染色質量的穩定和提高。經實際運行表明，該系統運行可靠，節能增效顯著。

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.
Key words dyeing wind machine; regulate speed by transducer; single-chip computer; control by permanent tension; control by permanent velocity
