A Feedback Scheduler for Real-Time Controller Tasks

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

The problem studied in this paper is how to distribute computingresources over a set of realtime control loops in order to optimizethe total control performance. Two subproblems are investigated: howthe control performance depends on the sampling interval, and how arecursive resource allocation optimization routine can be designed.Linear quadratic cost functions are used as performance indicators.Expressions for calculating their dependence on the sampling intervalare given. An optimization routine, called a feedback scheduler, thatuses these expressions is designed.
