| Research Abstract |
This research clarified safety function in control laws to reduce the frequency of events that a physical value in a control system deviates from its normal operating-range. The deviations can be caused not only by system destabilization but also by fluctuations of transient responses. In order to quantitatively establish the contribution of the safety function in control laws for risk reduction, this research established a quantitative assessment framework for obtaining the frequency of the deviations by using a performance index for the fluctuations of transient responses. Furthermore, this research also established a realization framework for the safety function in control laws, which can supplement ordinary safety-related systems in risk reduction according to international safety standards such as IEC 61508.
