Degradation Modeling and RUL Estimation of Deteriorating Systems in S-Plane

Degradation modeling and RUL estimation of systems are two essential problems in the research field of prognostics and health management. In the literature, one usually deals with these problems in the time domain. Here, we propose another perspective on this subject by studying the degradation modeling and RUL estimation in the s-plane. The study is based on a well-known mass-spring-damper deteriorating system. A complete procedure consisting of data collection, degradation indicator implementation, parameters estimation, failure definition and RUL estimation for the considered system is outlined. Some numerical experiments have been carried out to illustrate the procedure.
