Heuristics for Scheduling Periofic Complex Real-Time Tasks in a Distributed System

Real-time scheduling method for networked discrete control systems

“…In these papers, the MADB is obtained using the Ricatti equation approach, which yields conservative delay bounds. A scheduling method was presented in the NCS with Fieldbus networks (Beauvais & Deplanche, 1995;Cavalieri, Stefano, & Mirabella, 1995). But those papers did not consider the MADB, which were important in control applications.…”

“…A dynamic scheduling algorithm modified from the rate monotone scheduling algorithms was presented for periodic and sporadic data in Fieldbus networks (Raja et al, 1993). A heuristic algorithm was presented for periodic tasks only (Beauvais & Deplanche, 1995), but it did not support sporadic data. The several algorithms for dynamically scheduling of NCSs were proposed Zuberi & Shin, 1997).…”

H-infinity control for networked control systems (NCS) with time-varying delays

“…In addition, [ 2,4,7 -9 ] dealt with unknown time-invariant delays in a given range, and reported some maximum allowable delay bounds (MADB) within which the stability of the system is guaranteed. [ 8] used Ricatti equations to improve the MADBs in [ 2,4,7 ], and [ 9 ] further improved the results in [8]. Nevertheless, the stability criteria obtained were very conservative.…”
