Analyzing the Impact of Data Errors in Safety-Critical Control Systems
(2003) In IEICE Transactions on Information and Systems E86-D(12). p.2623-2633- Abstract
- Computers are increasingly used for implementing controlalgorithms in safety-critical embedded applications, such asengine control, braking control and flight surfacecontrol. Consequently, computer errors can have severe impact on the safety of such systems. Addressing the coupling of control performance with computer related errors, this paper develops a methodology for analyzing the impact data errors have on control system dependability. The impact of a data error is measured as the resulting control error. We use maximum bounds on this measure as the criterion forcontrol system failure (i.e., if the control error exceeds a certain threshold, the system has failed).In this paper we a) develop suitable models of computer faults for...

An automobile slip-control brake-system is used as an example showing the viability of our approach. (Less)
