Abstract: A multivariable fuzzy control strategy was proposed for the heat setting machine in post-procedure of printing and dyeing industry.In this strategy,the temperature field was controlled by means of three hierarchical subsections; each subsection was regulated with single fuzzy control loop so that the single loop temperature can be kept more precise.Based on this, a forward multivariable fuzzy controller was introduced for resolving the problems of subsections interference and temperature distributing uneven.Finally, the control strategy was completed in a real printing and dyeing process using SIEMENS PLC,the practical results show that the proposed approach is better than conventional PID approach.
