The field of prognostics has received increased attention due to its potential to provide early warning of failures, forecast maintenance as needed, and reduce lifecycle costs. This book provides a basic understanding of Prognostics and Health Management (PHM) and the techniques being developed, presents the state of the art in sensor systems for in-situ health and usage monitoring, discusses the various models and algorithms that can be utilized for PHM, and provides an overview of the challenges and opportunities for research and development in PHM for electrical and design engineers.
