Abstract
The effect on air temperature of variations in heater power for a forc ed convection overt were modelled. The transfer functions for five ope rating ranges, from 140 degrees C to 236 degrees C, were determined ex perimentally. The oven power control was excited using a pseudo-random binary signal and the resulting effect on the air temperature was mea sured. From this information, transfer functions in the ARMAX form wer e determined. It was found that while the denominator coefficients of the system do not vary for different ranges of air temperature, the nu merator coefficients of the system do vary significantly.
