Enhancing dependability and energy efficiency of cyber-physical systems by dynamic actuator derating

Plant-Cyber Tradeoffs in Frame-Based Cyber-Physical Systems

“…If it is within reachable distance of the SSS envelope, the control updates become critical and faulttolerance must be used to ensure that timing requirements are strictly met. Most of the time, however, the system is far away from the edge of its SSS and this can exploited appropriately to reduce pressure on the cyber platform [19]; it is this situation that we are concerned with here.…”
