Smart Low-Cost Electronic Module for Simultaneous Sensor and Process Faults Moni, Phase I

Completed

Description

The detection and isolation of air vehicle process failures is difficult because air vehicle dynamics are nonlinear and the vehicle has many important and complicated sub-systems. The fault diagnosis performance is further complicated by the presence of sensor failures. In this proposal, Intelligent Automation, Incorporated (IAI) proposes a novel approach to perform simultaneous diagnosis of sensor and process faults for air vehicles. This algorithm can be embedded into low cost electronics. First, two independent residual vectors (RVs) for detection and isolation of the sensor and process faults are built. This is in sharp contrast to conventional methods, which can deal with either sensor failures or process failures but never both. Second, to isolate faults, the RV is transformed into a set of structured residual vectors (SRVs), where one SRV is made insensitive to a specified subset of faults, while remaining sensitive to other faults. The proposed technology is relevant to this subtopic because we will develop an electronic module that can be embedded in low cost sensor electronics to quickly identify both sensor and process faults.

How to get involved

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
