分布環(huán)境下印染機溫度自適應(yīng)控制系統(tǒng)的研究

本文通過分析印染機溫度系統(tǒng)的特點，首先實現(xiàn)兩通道之間的解耦，同時針對印染機溫度系統(tǒng)的純滯后及參數(shù)大范圍緩變的情況，采用自適應(yīng)內(nèi)?？刂品椒ǎㄟ^在線辨識系統(tǒng)參數(shù)，并相應(yīng)修改解耦參數(shù)，克服了模型辨識精度與辨識計算量的矛盾，提高了系統(tǒng)的魯棒性，對不等延時的耦合系統(tǒng)提供了一種控制方法。

?On the analysis of the characteristics of dye jigger and by means ofthe decoupling the two channel temperature, an adaptive IMC method is proposed in this paper. Due to the system parameter varying in large scale, the control parameter is adjusted according to the online RLS parameter estimation. And it is finished in remote computer and the communication between master PC and filed controller is via CAN bus. This is a method to dealing with a couple-system with the different delay.
