Abstract:

This paper studies lifetime of automatic control systems to make the system tolerant to faults based on importance measures. The system lifetime can be divided into different phases, where the key components that can cause the system to fail can be different. Such key components can be identified by importance measures, which can guide the reliability design of control systems. In this work, through importance analysis, reliabilities and importance degrees of system components (e.g., sensors, actuators, process components) and sub-systems are first computed. Based on importance analysis results, different automatic control schemes are then developed and integrated. At last, the optimization design of automatic control systems is investigated to improve the system performance in term of system reliability or lifetime.
