oFault tolerant Model Predictive Control for a de-manufacturing plant

The diffusion of electronic board is constantly increasing due to the wide spreading of mechatronics products. End of life management of such type of products is not currently approached in terms of process efficiency and environmental effects in a global perspective. This topic is critical from an environmental point of view and represents a big opportunity for the manufacturing industry. To respond to this lack, ade-manufacturing pilot plant has been developed by CNR-ITIA in Milan.The plant is designed for testing, repairing and disrupting electronic boards, and is currently composed of a multi-path transport line and four machines. A primarily role is played by the conveyor system, that is able to guarantee an efficient routing of the boards in the network allowing to avoid bottlenecks, starvation and maximizing throughputs. This is due to the implementation of a multi-level control strategy inwhich, at the higher level, an MPC controller manages the movement of the pallets to optimize the performances while, at the lower level, PLCs acquire the sensor signals and drive the actuators.This Thesis aims to increment the reliability and the performance on the transport line of the pilot plant.
