Course content
This course is designed to provide the students with a good understanding of the basics of real time systems design. The course includes basic principles of real time programming: processes, synchronisation, communication and scheduling in real time systems and functions of real time operating systems. Since real time control represents one of the most important areas where the real time systems are applied, the course includes also an introduction into digital control, computer implementation of control algorithms and distributed control systems. Topics of the lectures Real-Time Systems, definitions, hard versus soft real time systems, real time control systems, application examples. Commonly used approaches to real-time scheduling, scheduling of periodic tasks, priority driven scheduling, resource access control. Inter-process communication synchronisation, deadlock, semaphores, queues Real Time operating systems. Sampling of continuous systems, discrete models of continuous systems, state space and transfer function models, Z transform. Design of digital controllers, digital approximation of continuous PID controllers, digital controllers with optimised structure.. Implementation of digital control algorithms, selection of sampling period, aliasing, effect of finite word length, fixed po int and floating point computation, quantisation effects, effect of the computational time delay. Distributed control systems, communication channel delays and their effect on control performance. Architecture and programming of industrial control systems, connection of logical and digital control in modern PLC systems. Laboratories and seminars The topics covered in lectures are practised in computer laboratory using selected real time operating systems and industrial control systems Rockwell Automation. The basics of digital control are practised using Matlab and relevant toolboxes.

Learning outcomes
This course is intended to provide the students with good understanding of the most important methods of real time systems design, analysis and programming. The main focus is on real time control systems. However, the majority of the explained principles and methods can be used for all real time systems in general.
Graduates from this course will obtain good knowledge in the field of real time systems design, analysis and programming.
