The paper deals with combined discrete-event and continuous-time simulation of distributed data communication and control system (DDCCS) networks for autonomous manufacturing plants, power and chemical plants, and advanced aircraft and spacecraft. The time-varying and (possibly) stochastic delays, introduced by the network, occur in addition to the usual sampling time delay in digital control systems. The delay and throughput characteristics of the Society of Automotive Engineers (SAE) linear token bus, SAE token ring and MIL-STD-1553B protocols have been analyzed in view of the DDCCS network design requirements. Simulation results are presented to illustrate how the network-induced delays could degrade performance and stability of the controlled process.
