Research on a soft real-time scheduling algorithm based on hybrid adaptive control architecture

Abstract

Aiming at the time-varying and non-linear characteristics of CPU resource real-time scheduling model, a soft real-time scheduling algorithm based on the hybrid adaptive feedback control architecture is presented. The hybrid control strategy solves the non-linear of real-time system effectively, and the general linear feedback control is realized through using the mutual exclusive relation of the saturation zone of utilization and miss ratio. Meanwhile, the adaptive control strategy is designed to ensure the system stability when the time-varying parameter is varied greatly. The steady and dynamic response performances are improved. The utilization of resource is increased.</p
