Abstract
A method for detecting errors in a sensor at a gas cylinder is implemented by a pressure estimation computing device including a processor and a memory device coupled to the processor. The method includes receiving a first pressure measurement from a first sensor associated with a gas cylinder, receiving a design schema describing an intake manifold, the intake manifold included within the gas engine, segmenting the design schema into a plurality of segments, defining a fluid dynamics model associated with each of the plurality of segments, defining a plurality of interconnected 2-port elements based on the plurality of fluid dynamics models, estimating a second pressure measurement for the gas cylinder based on the plurality of interconnected 2-port elements, comparing the first pressure measurement to the second pressure measurement, and determining that the first sensor is in an anomalous state.
