In order to solve the problem of tension control in the actual unwinding process of the lithium battery diaphragm slitting machine, the dynamic model of diaphragm and slitting machine unwinding system is constructed in this paper based on the diaphragm deformation in the unwinding system during the sampling period, in view of the nonlinear system characteristics of the unwinding system and the unstable diaphragm tension caused by the uncertain interference and the inaccurate model in the unwinding process. Considering the unwinding system characteristics of multi-output and strong coupling between outputs, a multi-variable comprehensive sliding surface for balancing unwinding diaphragm tension and unwinding speed, and a sliding mode controller for controlling the diaphragm tension in unwinding process are designed. And the stability of the sliding surface and the controller is proved. The fault-tolerant improvement of the sliding mode controller is carried out for practical engineering application, and the differential tracking disturbance observer is proposed to quickly estimate and compensate the external disturbance of the system. Finally, the results of the comparative experiments verify the effectiveness of the proposed diaphragm tension control scheme.

The process of wrapping with plastics to better ensure the safety of the goods are mostly done, such as goods before being put into the trunk of the plane or when the industrial product to be delivered in long distances. In the wrapping process, the tension of the tension of the plastic (wrapping material) is very important to keep its value so that it will produce a wrapping that is in accordance with the desired. In this paper will be presented about the implementation of PID (Proportional Integral Differential) controller for tension control on wrapping machine. The system consists of a three phase induction motor as a drive in the unwinder and rewinders, PIDs of the PLC, inductive proximity as a plastic tension sensor, and a PC for data entry and system monitoring. The tension control of the plastic wrapping material is carried out by manipulating the unwinder velocity for the rewinder speed which is maintained at a constant speed. The speed difference between the two motors (unwinder and rewinder) will produce tension. To get good control performance, PID parameter tuning is required. From tuning using 3 methods (reaction curve method, tuning PID TIA PORTAL tool and Dotx PID tuner application), the best result resulted with 3.3% overshoot response, 1.7 second rise time, 3.2% settling time second, there is 1 oscillation and steady state error of 0.263%.

To deal with the nonlinear coupling, strong disturbances and parametric uncertainties existing in the multi-motor web-winding system, a robust decentralized H ∞ control method is proposed in this paper. First, the whole web-winding system is considered as a synthetic system composed of several subsystems. Giving that some parameters are time dependent and set points are modified during the winding process, each subsystem can be seen as a dynamic interval system and interval matrix is introduced. Then, a robust decentralized H ∞ controller is designed to attenuate tension fluctuations introduced by the external disturbances and interaction between two consecutive subsystems. Sufficient condition for the existence of robust decentralized H ∞ control law is presented in terms of linear matrix inequality. Finally, some simulations and experiments are conducted with the conventional decentralized controller and the proposed controller. The comparative results show that the proposed control scheme greatly improves the control performance of the web tensions.INDEX TERMS Multi-motor web-winding system, robust decentralized H ∞ control, linear matrix inequality (LMI), interval matrix, tension control.
