Dynamic optimal control for aperiodic soft real-time system
非周期软实时系统的动态最优控制方法

The aperiodic soft real-time system with random task arrival and unpredictable task execution time was studied,and a dynamic optimal control method for DM scheduling algorithm based on the multiple priorities queuing system was proposed.The method can statistically guarantee the schedulability of soft real-time systems,and meanwhile it can guarantee the Quality of Service(QoS) of incoming tasks and improve the throughput of system.Finally,an example show that this method is capable of improving the actual utilization and decreasing the deadline miss ratio of system.Therefore,it is an efficient workload management method.
