Managing Complex Temporal Requirements in Real-Time Control Systems
Design and implementation of motion control applications includes the transition from control design to real-time system implementation. To make this transition smooth, the specification model for the real-time system should allow also for temporal requirements other than deadlines, e.g., deviation from nominal period time of an activity, end-to-end timing constraints, temporal correlation between different sampling tasks and constraints on temporal variations in output. Many realtime systems in industry today are based on pre-emptive priority based run-time systems, and hence, the temporal requirements should be fulfilled by correctly assigning attributes such as priorities and offsets to the tasks executing in such systems. Assigning priorities and offsets in order to fulfill complex temporal requirements originating from control design and computer system design is a hard task that should be supported by powerful methods and tools. In this paper we propose a method, which by assign...
