Aircraft Motor Controller Multi-Core Architecture for Prognostic Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft motor controllers with single core processors are inadequate for processing prognostics and diagnostics data, limiting their ability to perform maintenance and health predictions, and potentially leading to faults due to insufficient data handling capabilities.
Innovation Solution
A multi-core processor is introduced, featuring separate control and prognostic cores that allow for independent processing of power management and diagnostics data, eliminating the need for a separate power supply and preventing interference with motor control software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single core processor is used in the motor controller, then the device complexity is reduced and ease of manufacture is improved, but the ability to process prognostics and diagnostics data is insufficient
Solution Approach 1:
The processor is segmented into multiple independent cores: control cores for motor control functions and prognostic cores for diagnostics and predictive maintenance. This segmentation allows each core to specialize in specific tasks, improving overall data processing capability while maintaining manufacturing feasibility through modular architecture
2Adaptability or versatility
If a separate prognostic processor is added to process diagnostics data, then the data handling capability is improved, but the device complexity increases and additional power supply is required
Solution Approach 1:
The prognostic processor is merged with the control processor into a single integrated multi-core processor unit. This combination eliminates the need for separate power supplies and reduces overall device complexity while maintaining enhanced data processing capabilities through the dedicated prognostic cores
3Adaptability or versatility
If a multi-core processor with separate prognostic cores is used, then the prognostics and diagnostics data processing is improved, but the manufacturing complexity increases
Solution Approach 1:
The multi-core processor is designed with universal functionality where control cores handle motor control tasks and prognostic cores handle diagnostics and predictive maintenance. This multi-functional design allows a single processor unit to replace multiple separate devices, simplifying manufacturing integration despite the increased internal complexity
