Contents
A real-time system is characterized by the fact that it is not only the result of the calculation that matters, but also when the result is produced. Computers that are used for feedback control are good examples of real-time systems, since they must operate periodically in a time-scale that is dependent on the dynamics of the controlled process, while at the same time they must be able to respond to external events, often within a given time interval. Two types of examples are industrial control systems used in, e.g., process automation, and embedded control systems for, e.g. avionics, autonomous vehicles and robotics. The aim of the course is to study methods for design and implementation of real-time systems for control applications. The implementation part of the course is performed as a project.
