RESEARCH ON A SOFT REAL-TIME SCHEDULING ALGORITHM BASED ON THE HYBRID LINEAR FEEDBACK CONTROL STRUCTURE

Aiming at the time-varying and non-linear characteristic of CPU resource real-time scheduling model, this paper presents a soft real-time scheduling algorithm based on the hybrid feedback control structure. This algorithm solves the non-linearness of real-time system effectively. The general linearized feedback control is realized. Meanwhile, the robustness is demonstrated when the system parameter is varied. The steady and dynamic response performances are improved. The utilization of resource is increased.
