- Abstract
- This paper presents the non-linear modeling of the web(film) transfer system and design of (robust) sliding mode controller bared on the developed model. The system model shows change in the roll-radius during winding and unwinding of the web. The change of inertia makes the web transfer system time-varying and nonlinear. In designing a robust controller, two major objectives are considered. The first one is that the web transferring velocity tracks a given reference velocity; the second one is that the web tension is regulated at a certain value. To verify the control algorithm, the proposed algorithm is compared with a conventional PID controller through a campater simulation based on simulink model. Computer simulation study shows that the proposed robust sliding mode controller is an improvement over the PID controller for various control inputs.
