Research on Improved EDF Scheduling Algorithm Based on Error

Schedule plays a significant role in networked control systems of multi-tasks. So it is an important research on scheduling algorithms of NCS. The class data structure of true-time box is introduced at first. On top of that, it is mainly discussed about the improved EDF algorithms. The EDFE algorithm is put forward. It has considered not only characters of the controlled objects, but also the control capability. Finally the simulation example about the EDFE algorithm is done using the truetime box. It is proved that the EDFE algorithm has a better effect on the NCS.
