Dependable system upgrade

The rate of innovations in technologies has far exceeded the rate of adopting them in at least the past 20 years. To fully realize the potential of innovations, a paradigm shift is needed, from a focus on enabling technologies for completely new installations to one which is designed to mitigate the risk and cost of bringing new technologies into functioning systems. In this paper, we show that real time control software can be dependably upgrade online via the use of analytically redundant controllers.
