Abstract
Conference Title: 2014 6th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT) Conference Start Date: 2014, Oct. 6 Conference End Date: 2014, Oct. 8 Conference Location: St. Petersburg, Russia In this paper, TMR Sensors are applied to a fault-tolerant direct sensor to actuator (S2A) architecture for Ethernet-based Networked Control Systems (NCSs). The architecture is studied using switched Fast and Gigabit Ethernet. It is shown analytically and verified via OMNeT++ simulations that the architecture succeeds in meeting system end-to-end delay and strict zero packet loss (no over-delayed packets) requirements when using Gigabit Ethernet. Reliability modeling is carried out to quantitatively assess the benefits of the TMR sensors architecture when compared to an S2A fault-tolerant controller architecture.
