Control systems with critical functions or Quality of Services (QoS) constraints are supported by computers. A correct behaviour of the system does not only depend on correctness of results but also on time instants at which they are produced. Such a dual requirement characterizes real-time systems. A computerized control system must be reactive towards the controlled systems or QoS metrics to guarantee. In most of implementations, the control software is decomposed in a set of parallel tasks upon one or several processors. Before using the real-time system, designers must verify that temporal constraints will be respected throughout the system life. To ensure that task deadlines will be met, scheduling algorithms must be designed and configured according to the system specifications and the environment of the controlled processes. Finally, the system is validated by a detailed scheduling analysis in order to prove the temporal constraints will be met.
