Abstract: The robust multi-step prediction control method based on an uncertain color model in dyeing process is presented to control the pressure, temperature and speed of the dyeing machine, previously, due to the unstable parameters of the grey fabric after pretreatment, its control was utterly depended on the engineers′ experience. Having developed the robust multi-step prediction control method, the pressure, temperature and speed of the dyeing machine can be adjusted according to the acquired data by on-line detection of the pressure, temperature, and speed of the machine and the color value of the semi-finished goods. Examples were also given to verify the result of this approach.
