Self-Healing from a PHM Perspective

This work presents an approach that addresses the concept of self-healing as a contingency management approach framed in the PHM perspective. The study is centered on developing strategies for extending the operation of power-electronics to motor-drives and electric machinery. The strategies proposed are capable of maintaining operational functionality at reduced performance during various fault conditions, as well as optimization of the impact of stresses in the failing parts in the overall system. The main tradeoffs of the techniques are discussed and evaluated.
