In industrial manufacturing systems, one or more client motors are often arranged to follow the velocity of the master motor. The speed difference between these motors will affect the tension of the product. Hence, the synchronized control and the tension control are the important research topics in the manufacturing process. This paper proposes a novel modified multi-input-multi-output (MIMO) discrete integral variable structure control (DIVSC) for the synchronism and tension control of dual motor systems. By the Grey model theory, the unknown model of tension control can be established on-line to be a pseudo-Grey model. Based on these pseudo-Grey models, the model-based MIMO DIVSC can proceed with the design procedures. Finally, a prototype of the dual motor system is developed for testing the performance of the proposed control scheme. Experimental results will show the robust potential and the practicability of the proposed controller.
