On the Effect of Transient Data-Errors in Controller Implementations

Gäfvert, Magnus LU ; Wittenmark, Björn LU and Askerdal, Örjan (2003) American Control Conference, 2003 In Proceedings of the 2003 American Control Conference, vols 1-6 4. p.3411-3416
Abstract
Computer-level faults leading to data errors in computations arepredicted to occur increasingly frequent in future microprocessors.This work discusses the impact of such errors on closed-loopperformance in implementations of digital control systems. A method torender a control system more robust to data errors by introducingartificial signal limits and then combine them with an anti-windupscheme is presented and exemplified. Accepted for publication.
