Abstract
In this paper, we propose a method to deal with the control of an electroplating line without stopping the production. The considered system is running in repetitive functioning mode, and it is modelled by a P-time event graph. The main objective is to switch the number of parallel resources to maintain a resource while the production is assumed to be always running. So, two functioning modes appears: normal and maintenance modes. Each mode is described by a state space model written in the standard algebra and a global model corresponding to a switching system which is a class of hybrid systems is obtained. Using model predictive control technique, stabilizing state feedback gains are computed over an infinite horizon respecting the time constraints while maintenance is performed.
