PROBLEM TO BE SOLVED: To acquire the optimum correction rotation speed of a compressor 40 with respect to a plurality of arbitrary input values by a simple algorithm with less man-hour for development. SOLUTION: A plurality of model control points pa, pb, pc are set in a two-dimensional diagram pattern formed of a temperature deviation En between a target after-evaporator temperature TEO and after-evaporator temperature Te and of the deviation change rate Edot of the temperature deviation En, so that an actual control coordinate point px in a present input value is specified. A model control pattern Px at the actual control coordinate point px is synthesized from the model control patterns Pa, Pb, Pc of morphed coordinate points pa, pb, pc previously stored in memory. In the synthesization, the distances between the morphed coordinate points pa, pb, pc and the actual control coordinate point px are employed for weighting to be synthesized by a morphing method. A target rotation speed IVOn is read from the synthesized model control pattern Px. COPYRIGHT: (C)2010,JPO&INPIT |
