Reducing the Reliability Over-Cost in Reconfiguration-Based Fault Tolerant Control Under Actuator Faults

This note addresses reconfiguration-based fault tolerance under actuator faults, for linear time invariant systems. Based on the concept of bottom-up extensible controls, a fault tolerance scheme that mixes the passive and active approaches is designed to recover all recoverable faults, and an algorithm is proposed to reduce the reliability overcost with respect to previous designs.
