Abstract

Because some timing-constraints of a controller task may be not determined as a real-time system engineer thinks of, its scheduling with uncertain attributes can not be usually and simply dealt with according to classic manners used in real-time systems. The model of a controller task with fuzzy deadline and its scheduling are studied. The dedication concept and the scheduling policy of largest dedication first are proposed first. Simulation shows that the scheduling of controller tasks with fuzzy deadline can be implemented by using the proposed method, whilst the control performance cost gets guaranteed.
