?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.
