Weakly hard real-time systems
TL;DR: This paper defines four temporal constraints based on determining a maximum number of deadlines that can be missed during a window of time (a given number of invocations) and provides the theoretical analysis of the properties and relationships of these constraints.
Scheduling dependent real-time activities
TL;DR: This work may improve the current practices employed in designing and constructing supervisory control systems by encouraging the use of modern software engineering methodologies and reducing the amount of tuning that is required to produce systems that meet their real-time constraints--while providing improved scheduling, graceful degradation, and more freedom in modifying the system over time.
Journal ArticleDOI
On condition/event systems with discrete state realizations
TL;DR: This paper introduces condition/event (C/E) systems as a class of continuous-time discrete event dynamic systems (DEDS) with two types of discrete-valued input and output signals: condition signals andevent signals and shows that C/E systems with discrete state realizations are necessarily time-change invariant.
Journal ArticleDOI
The real-time supervisory control of an experimental manufacturing cell
TL;DR: The paper provides an overview of the automated manufacturing field, and introduces supervisory-control-system development, and illustrates the applicability of the controlled-automata based approach to supervisory control of industrial automated manufacturing systems.
Journal ArticleDOI
Use of novel adaptive digital feedback for magnetic measurements under controlled magnetizing conditions
TL;DR: In this paper, a computerized automated adaptive digital feedback system built for measuring magnetic properties of soft magnetic materials under fully controlled nonsinusoidal flux density waveforms is presented. But the system is limited to the frequency range of 0.5 Hz to 2 kHz and the peak flux density up to 90% of saturation.
