This paper presents a method to analyze and design the safe control system using the safety function. The safety function is defined to represent a safety domain in the state space. Using a model of controlled plant and a number of control logic examples with appropriate predetermined safety function, we can evaluate whether the whole system is safe or not. Illustrative example shows that the proposed...
This paper provides an approach of safety verification of logic control system with application of Gröbner bases method. We propose a method to analyze and design a safe control system using a safety function. In this case, the safety is defined to represent a safety domain in the state space. Using a plant model and controller examples with appropriate predetermined safety function, we can evaluate...
