將卷染機(jī)的控制系統(tǒng)從直流電機(jī)拖動(dòng)、自耦調(diào)壓器有級調(diào)速改造為交流電機(jī)拖動(dòng)和變頻器無級調(diào)速。通過對調(diào)節(jié)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(jī)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(tǒng)可自動(dòng)對被染織物進(jìn)行恒速與恒張力控制，以利于染色質(zhì)量的穩(wěn)定和提高。經(jīng)實(shí)際運(yùn)行表明，該系統(tǒng)運(yùn)行可靠，節(jié)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
