Table 5 Methods of fault imposition for each of the multi-zone VAV AHU #1 faults.
From: Building fault detection data to aid diagnostic algorithm creation and performance testing
Input Scenarios | Method of fault imposition | |
|---|---|---|
Fault type | Fault intensity | |
Outdoor air temperature sensor bias (x is the true value, x′ is the faulted value) | x′ = x + 1(°C) | Add bias to sensor output |
x′ = x + 2(°C) | ||
x′ = x + 4(°C) | ||
x′ = x − 1(°C) | ||
x′ = x − 2(°C) | ||
x′ = x − 4(°C) | ||
Unfaulted | — | |
