Self-Adaptive Software for Fault-Adaptive Control

Self-adaptive software is a technology that allows building fault-adaptive control systems: control software that can survive faults in the system under control, and in the control software itself. This form of self-adaptive software requires capabilities for the detection and isolation of faults when the system is in operation, and then taking appropriate control actions to mitigate the fault effects and maintain system operation in the best way possible. This paper discusses heterogeneous model-based approach for building fault-adaptive control software, with special emphasis on the modeling schemes that describe different aspects of the system functionality and behavior at different levels of granularity. The computational architecture is applied to design and run experiments on a fault-adaptive control software of an airplane fuel system.
