Apply discrete integral variable structure control to synchronization and tension control of dual motor rolling systems

In industrial manufacturing systems, the one or the 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 project proposes a novel modified MIMO DTVSC for the synchronism and tension control of dual motor system. By Grey model theory, the unknown model of tension control can be on-line established to be a pseudo grey model. Based on these pseudo grey models, the model based multi-input-multi-output (MIMO) discrete integral variable structure control (DIVSC) can proceed with the design procedures. At the same time, 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.
