Structured approach to the design of automation systems through IEC 61499 standard

摘要

The main objectives of this study is the conception of an Engineering Support System (ESS) for sustainable optimization of automation tasks supervision, through a set of formalisms, methods and tools introduced to support the control engineer in the design phase of optimized supervisor solutions. The ESS is based on the IEC 61499 standard for distributed automation, considered as technological reference for the development of automation logics for the new generation of manufacturing systems (CPS). It implements a new formalism for the control problem description and specification, guiding the control engineer within all the control design phases, in order to obtain high performance manufacturing systems while pursuing optimization of key parameter indicators, including for example minimal energy consumption and emissions. To such an aim it enables the possibility to formalize the control supervision problem into a constrained optimization problem to be solved with the most appropriate optimization algorithm selecting the most interesting optimization objectives. Finally, an innovative virtual commissioning platform is adopted. It allows to validate the developed automation tasks supervision system using the real targets running the control solution connected with the virtual model of the system to be controlled in place of the real one.
