Multi-phased development of a real-time control system and its validation through real-time simulation

In this paper we describe a multi-phased development method for a real-time system based on the TMO (time-triggered message-triggered object) model and its validation by using the real-time simulation technique. Through multiple development phases, the system/subsystem model based on the TMO model is applied. In each phase, real-time simulation is performed to validate the model developed in the phase. In order to examine the effectiveness of our approach, we have applied the approach to the development of the SIS (safety injection system) simulator and it shows the same functionality and timing behaviors as the SIS simulator currently used in the KEPRI (Korea Electric Power Research Institute).
