Feedback control systems with cyber fault-management mechanisms: Modeling and tradeoff analysis for simple examples |
Abstract | ||
|---|---|---|
The impacts of cyber-fault resolution techniques on the dynamics of feedback control systems are explored, using simple case studies. Specifically, for a three-state DC motor model, simple control schemes implemented using embedded microcontrollers are modeled as being subject to freeze faults, which are resolved using watchdog-timer technologies. Simulations are undertaken to characterize the impacts of the faults and fault-resolution mechanisms. Also, a formal analysis of freeze faults and fault resolution is undertaken for a singlepole plant with proportional control. It is found that watchdog timers can reduce severe impacts of faults occurring during the control system's transient, but may increase susceptibility to other faults. |
