This paper addresses system control quality in a real-time context. Comparing the impact of sampling period reduction by a Feedback Scheduler, using three different processor utilization bounds, we stress the antinomy of control quality and schedulability. We then measure statistically the impact of scheduling artefacts (task jitters, input/output delays) to outline the main factors causing this antinomy.
