The Smart System as a CPS

Abstract

With a rise of social interests for preservation of global environment and efficient use of resources, the innovation of technology is required to realize the smart system mainly for social infrastructures. This paper clarifies the concept of smartness and explains the difference between the large-scale engineering system and the smart system. In order to show the image of smart system, the requirements and technology realizing them of smartness are described concretely on the smart mobility as an example. The smart system integrates various systems with different characteristic. Then it is called the cyber physical system (CPS) in the field of system theory. On the CPS as a system model of the smart system, are explained its basic concept, control function, system structure and autonomy which features CPS and is required for realization. For the development of CPS applications for smart systems, their feasibility is discussed on autonomous subsystems, networking and information technology (NIT) supporting CPS and control technology establishing smartness. The possible course of technical developments is concluded for the practical implementation of smart systems in future.
