Cyber-Physical Systems Design (in English)
CPSa Acad. year 2020/2021 Summer semester 5 credits
The Cyber-Physical Systems combine cybernetic (computation and/or communication) and physical properties (motion or other physical processes). The application of such systems covers automotive, flight control and defense systems, critical infrastructure control (power grids, water resources, communication systems), energy management and storage, transportation control and safety, communication systems, robotics and distributed robotics (telemedicine), medical technologies, systems for assisted living, consumer electronics, toys and other smart devices. These devices interact in physical world through computer controlled algorithms. Design of the CPS control algorithms is a challenging discipline considering their tight coupling to physical systems behavior. An important design aspect to be considered is the correctness of the control algorithms itself, as the execution of critical control tasks depends on their correct function, as is the case in aircraft and/or car collision avoidance in automatic or autonomous modes, respectively. The aim of the course is to find an answer to an important social question, how to responsibly design critical Cyber-Physical Systems on whose flawless function depend human lives.
Language of instruction
Subject specific learning outcomes and competences
A successful graduate will acquire the understanding of basic CPS principles and knowledge in the design and analysis of computer systems integrated into real physical processes. The acquired knowledge will allow for a qualified insight into the system abstraction and architecture, and will simultaneously support the mastering of model and control system designs while using adequate safety specifications to fulfill desired CPS performance targets. The acquired knowledge and skills will support verification of adequate CPS models while taking into account the expected effects of the environment on their function.
The aim of the course is to stimulate an understanding of the design and analysis of Cyber-Physical Systems (CPS), which integrate computer systems into physical processes. Simultaneously, the course also addresses the synthesis of highly reliable real-time systems. The design and programming of control systems in laboratory conditions is an integral part of the course.
Why is the course taught
In recent years there has been a significant improvement in the availability of precise and reliable sensors, high-performance actuators (servos) and embedded systems. Cyber-Physical Systems (CPS) combining computer software with physical components became a ubiquitous part of our daily life. Automotive, medical and aeronautical applications represent only a small fraction of the interaction between the automatic and intelligent machines and humans. The course will introduce the CPS design environment, while also addressing the compromises originating from the essential reliability and safety requirements. The presented CPS design framework will introduce the relation between the computer hardware and software engineering starting from the initial design draft up to the final system validation.
