Some issues of scheduling in Networked Control Systems
Huiying Chen · Computer Engineering and Applications Journal · 2007
The control performances of Networked Control Systems(NCSs) are considerably constrained by sharable computing and networked resources.Therefore,how to effectively schedule the periodic and aperiodic stream of information in NCS is a pivotal factor that impacts the system performances.From a real-time control perspective,the timing analysis and the theory of real-time scheduling in NCS are illustrated respectively,with special focus on real-time CPU scheduling strategies,network scheduling methods in NCSs,problems induced in scheduling and their compensatory techniques,schedulability analysis and scheduling optimization,and control and scheduling co-design.Furthermore,farther research directions in this field are also discussed in detail.
