Ridgetop's Adaptive Remaining Useful Life Estimator (ARULE) is a powerful reasoner to determine the remaining useful life (RUL) and state of health (SoH) of complex systems. Working from acquired sensor data, ARULE employs an advanced prediction method related to extended Kalman filtering (EKF) to produce new RUL and SoH estimates for each new sensor data point.
ARULE relies on diagnostic sensor data and a predefined model to produce an RUL estimate. It requires a sensor to “sense” data that are above a predefined “good-as-new” floor and below a “failed” ceiling. A new RUL estimate is produced based on changes to the model space; additionally, the new RUL estimate is used to produce a new SoH estimate.
ARULE is part of Ridgetop’s prognostics and health management (PHM) family of tools called Sentinel Suite™. In particular, ARULE is an integral part of Sentinel Power™, Sentinel Motion™ and Sentinel IT™, for advanced diagnostics and prognostics for power systems, rotational/vibrating systems, and networks, respectively.
