Enhancing Feedback Control Scheduling Performance by On-line Quantification and Suppression of Measurement Disturbance
2005 (English)In: Proceedings of the 11th IEEE Real-Time and Embedded Technology and Applications Symposium, 2005, 2-11 p.Conference paper (Refereed)
In the control of continuous and physical systems, the controlled system is sampled sufficiently fast to capture the system dynamics. In general, this property cannot be applied to the control of computer systems as the measured variables are often computed over a data set, e.g., deadline miss ratio. In this paper we quantize the disturbance present in the measured variable as a function of the sampling period and we propose a measurement disturbance suppressive control structure. The experiments we have carried out show that a controller using the proposed control structure outperforms a traditional control structure with regard to performance reliability and adaptation.
