Abstract:

This paper enhances a recently developed tool to analyze the mean-square stability of digital control systems implemented in computers or embedded processors with rollback recovery that are operating in harsh environments. In particular, closed-loop models are derived that allow the analysis of partial state rollback where not all the states are checkpointed and rolled back. The theoretical results are illustrated with the analysis of a stabilizing controller for the longitudinal dynamics of the AFTI/F-16 aircraft. This example is also used to determine the effect of longer checkpoint durations on the mean-square stability of the flight control system.
