Summary:The paper mainly researches the priority scheduling of multiple characteristic parameters, proposing a new hybrid scheduling algorithm based on priority table. In the general priority scheduling, the approach which judges the priority of task via one parameter can not fully reflect the influence of other parameters to scheduling. Based on the above issues, we consider to determine the task priority table uniquely via the Deadline Earliest First, Highest Value First and First Come First Serve scheduling algorithms with deadline, value and arriving time. The algorithm enriches the establishment basis of task priority, ensures prior scheduling for critical task in high-load conditions and decreases the Deadline Miss Rate. The NCS stable performance is improved. The validity of the algorithm is verified by the simulation of inverted pendulum networked control system.
