Elementary Fault Detection and Location Based on Physical Laws and M, A, & S

In this paper, issues and procedures for failure detection and failed item location in a specific category of systems are addressed. Sensor failure as well as system element failure is included. The category of systems addressed are those composed of power exchanging physical processes and those having equivalent mathematical model properties. The material is pertinent to the scenario in which rapid failure detection, rapid failed item identification, and rapid repair/replacement is important, a scenario characteristic of space exploration environmental monitoring and control system operation.
