Abstract

The relationship between the performance cost and the processor utilization of the real-time control tasks in different control phase was investigated, further more, a feedback scheduling system based on linear assignment algorithm was constructed, and in this system, processor utilization was assigned by feedback scheduler according to the control error, that is, real-time control tasks would get more processor utilization when its control error increases. Simulation results verified that the feedback scheduling system based on control error can improve the overall systems performance under limited computing resources
