EMI Control via System Design

This project implements a prototype knowledge based expert assistant to aid in mitigating electromagnetic interference (EMI) from hybrid electric vehicles (HEVs). The concept evolved from a broad investigation of HEV architectures, EMI causes, andcorrective actions during Phase I. The expert assistance includes cost, risk, and programmatic factors to provide prioritized recommendations and accompanying rationale to reduce EMI. The system, termed a Risk Model, is a practical approach to capture anddeliver HEV EMI mitigation aid to designers, program managers, operators, and maintainers. The Risk Model is useful in early stages of conceptual design through fault localization and corrective action after production and fielding. The project includesthe collection of detail electromagnetic environment effects (EEE) data for HEVs, both before and after corrective actions, to provide verification of mitigation techniques. The Risk Model provides diagnostic assistance for EMI localization. It providescost and EEE prognostics for different mitigation techniques.
