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.

Introduction, Real-time programming, Synchronization and mutual exclusion, Real-time kernels and operating systems, Periodic controller tasks, Computer implementation of control algorithms, Discretization of continuous-time controllers, Sampling of continuous-time systems, Input-output models of discrete-time systems, Sequence control using Grafcet, Scheduling theory, Integrated control and scheduling, Implementation aspects, Control over networks.

Examination details

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: Written exam (5 hours), three laboratory exercises, project. In the case of less than 5 registered students, the retake exams may be given in oral form.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
