Abstract

Based on recent research; very simple discrete-time control structures can be used to synthesise preemptive process schedulers for multitasking systems within a rigorous system-theoretical formalism. Doing so virtually eliminates any heuristics; and allows for a methodologically grounded analysis and assessment of the achieved performances. This paper introduces a Modelica library for the above purpose; at present still under development; and illustrates its use with some tests.
