The plant considered in this paper is a web system with winder, traction motor and unwinder. Transport system dynamics change dramatically due to the wide variation in roll radii and inertia. The effect of these changes is reduced by gain scheduling control. Industrial systems typically use decentralized PID controllers. In this paper, the authors present(More)
interferent error is the rate constant of the interfering substance (4). Because this rate constant is temperature dependent, the temperature differences occurring in the macro and micro creatinine methods may give rise to dissimilar acetoacetate rate constants, causing the former to show large negative ketone interference while the latter shows only slight(More)
This paper presents the study of an industrial accumulator (see figure 1) used in a web transport system. Different models based on physical laws have been built in order to understand the main characteristics of the accumulator and its behavior during transient phases. A mechanical equation is used for the calculation of the velocity of a roll and(More)
