<p>A control system, well suited for an aircraft, is operative with a process for analysis of system status by computing the most probable state of the system with single or multiple system feedback system failures. Sets of sensor signals are provided to describe the positions of various components of the aircraft, these sets being compared to reference sets to determine accuracy in feedback signals. Discrepancies with present or possible system states are noted, and the probability of each discrepancy is evaluated. This involves computations of probability from previously determined failure rates of various components of the system including sensors, subsystems operative with the sensors, actuators, and subsystems operative with the actuators. The joint probabilities of possible system states are calculated to determine the apparent state of the system to permit further operation of the system. Determination of reliability of subsystems includes mechanical and electrical components and various interconnecting parts such as connectors, cabling, and interfaces. <IMAGE></p> |
