<p>Disclosed is a control apparatus for a fuel reformer, which enables control with consideration of the nonlinearity of the thermal model of a reforming catalyst. An ECU (3) comprises a catalyst temperature sensor (21) for detecting the temperature of a reforming catalyst (11), a catalyst temperature estimation section (32) for estimating the catalyst temperature on the basis of a correlation model relating the catalyst temperature to the catalyst reaction thermal coefficient out of plural parameters by which the reforming reaction of the reforming catalyst (11) is characterized , a controller (30) for controlling the temperature of the reforming catalyst (11) according to the estimated temperature T CAT HAT of the catalyst temperature estimation section (32), and a model correction section (34) for defining plural correction weighting functions W 0 to W 4 with the catalyst temperature as the domain of definition, calculating plural local correction coefficients K CL0 to K CL4 by which the plural correction weighting functions are to be multiplied, respectively, from the detected temperature T CAT SNS of the catalyst temperature sensor (21) and the estimated temperature T CAT HAT of the catalyst temperature estimation section (32), and correcting the correlation model according to the plural correction weighting functions and local correction coefficients.</p> |
