As the Stennis Space Center (SSC) leads the push toward realization of integrated systems health management (ISHM) for new NASA exploration missions, the IEEE 1451 standard has emerged as the predominant interface for networking the smart sensors that monitor the health of complex aerospace Systems-of-Systems (SoS). Ridgetop Group joins the SSC effort by leveraging its state-of-the-art electronic power systems prognostics developed for the Ames Research Center (ARC) under NASA's companion integrated vehicle health management (IVHM) directorate. Non-intrusive monitoring of power systems' State of Health (SoH) can be facilitated by examining the power system response to an impulse load change, and extracting the characteristic frequencies of this response. The IEEE 1451 smart power sensor technology, which can be implemented or packaged as a single-board system or system on chip (SoC), is based on the extraction of the eigenvalues that comprise the damped sinusoidal "ringing" response of electronic power systems, including switch mode power supplies (SMPS) and electromechanical actuator (EMA) servo drive power stages. By default, the smart sensor's analog transducer output indicates the SoH or remaining useful life (RUL) of the entire power system, taking into account the health of all of the individual system components (e.g. SMPS output filter capacitor, feedback amplifier, PWM controller, etc). The analog output signal is set to a maximum value when the sensor detects that the power system is 100% healthy and a minimal value when the system has completely failed, or 0% healthy. A key, novel element of the proposed innovation is the ability of the smart power sensor to be reconfigured programmatically by the user. Individual system components can be monitored to determine the primary contributors to system wear-out and improve next-generation OEM designs.
