Abstract
A system and method is provided for predicting a physical quality such as temperature, the measurement of which tends to be hindered by a time-related impediment. A single sensor is configured to detect, in real time, the physical quality Qdetect, and one or more infinite impulse response filters are configured with time constants correlated to the time-related impediment. The infinite impulse filter(a) are configured to filter Qdetect to output a filtered quality measurement (Qfiltered). A processor is configured to calculate, in real time, the estimated or predicted quality Qestimate using Qdetect and Q filtered.
Claims15
A method for transforming physical quality data into an estimated measured quality, comprising:
- a) obtaining, with a sensor in real time, data representing a physical quality (Qdetect), wherein an impediment exists to the detection of the physical quality;
- b) filtering Qdetect through a first IIR filter (IIR1), wherein the IIR1 outputs Qfiltered1;
- c) calculating, with a processor in real time, the estimated measured quality (Qestimate) using Qfiltered1 and Qdetect.
