Abstract
Apparatus and methods for assessing component health for reconfigurable control are disclosed. In one embodiment, a method of operating a product includes monitoring a first diagnostic information of a component of the product, and monitoring a second diagnostic information of a system that includes the component. The first and second diagnostic informations are then combined, and based at least partially on the combined first and second diagnostic information at least one of the component and the system are reconfigured.
Claims14
A method of operating an aircraft, comprising:
- monitoring operating parameters of a component of the aircraft;
- monitoring system-level health of an aircraft control system including the component, wherein the system health is monitored to determine break points for health discrimination;
- processing the operating parameters and the system-level health to determine health of the component, including performing principal component analysis (PCA) to provide a reduced set of data, determining a scale factor from the PCA, and using the reduced set in conjunction with the system level health to determine a health assessment parameter for the component, wherein the breakpoints are combined with the scale factor to determine the health assessment parameter;
- and
- reconfiguring at least one of the component and the flight control system to compensate for the component during operation if the health assessment parameter indicates a degradation of the component.
