In the era of digitalization and the fourth industrial revolution, known as Industry 4.0, cyber-physical systems (CPSs) play an absolutely central role. They are the technological basis that makes it possible to seamlessly connect the physical world with the virtual world of information technology. But what exactly is behind this term, and what potentials do these complex systems open up for the future of industry and beyond?
Cyber-physical systems, often abbreviated as CPS, are intelligent systems that combine mechanical and electronic components with modern information technology and software. These systems are able to capture data from the physical world, process it digitally, analyze it, and in turn control or influence physical processes on the basis of this information.
These are embedded systems that collect information via sensors and intervene in the physical world via actuators. The ability to self-organize and adapt to changing conditions makes advanced cyber-physical systems a decisive factor in the development of complex applications in various fields.
The integration of cyber-physical systems is at the heart of how they work. They overcome the traditional separation between the digital and physical worlds by enabling a continuous flow of information and control. Sensors record physical variables such as temperature, pressure, and position, and convert these into digital data. This data is transmitted to central or decentral computing units via wireless or wired networks.
This is where the information is processed and analyzed, often using artificial intelligence. The knowledge gained is then used to intervene directly in the physical process via actuators (e.g., motors, valves).
The fields of application for cyber-physical systems are diverse and range from industrial production to everyday infrastructures.
CPSs in Industry 4.0 (smart factory)
In Industry 4.0, CPSs are the backbone of the smart factory. Here, they enable the complete digitalization and networking of production processes. Machines, products, and logistics systems communicate with each other, exchange status information, and largely control themselves.
Intelligent infrastructures (smart grids, smart homes)
CPSs make a significant contribution to the efficiency and security of critical infrastructures:
Autonomous systems and mobility
CPSs are indispensable in the field of mobility and robotics:
In the healthcare sector, CPSs enable new forms of patient care and monitoring:
Cyber-physical systems are the driving force behind the transformation of our industry and society. They enable the seamless connection of physical processes with computer networks, creating a new generation of intelligent, networked, and autonomous systems that have the potential to fundamentally improve our world.
