Modeling of a mechatronic system for automating the production of biomass pellets with the apparatus of Petri nets

The present work aimed to model the general stages of solid biofuel production, using an automated mechatronic system (AMS) for manufacturing pellets from wood residue and a Petri net. Based on the pellets characteristics a scheme of AMS for processing biomass raw matter was designed and a generalized Petri net was developed. The work was carried out considering the technological and auxiliary operations, performed by the systems' structural units. The technological process of biomass pellets production was determined and expressed in terms of nine global stages. The main nodes and states, and the transition tacts during the operation of the modeled Petri net for the AMS were proposed along with a schematic interpretation of the envisaged mechatronic pellet production system.
