PROBLEM TO BE SOLVED: To improve follow-up performance for an actual number of revolutions with respect to a change in the target number of revolutions by exerting feed forward control coping with a change in a static characteristic of a dynamo electric motor according to individual difference of the dynamo electric motor or a change in the installation thereof.SOLUTION: According to a primary function model indicating a static characteristic of a fan motor 42, a feed forward control section 220 calculates an amount Uff of feed forward control corresponding to a target number N*of revolutions. The primary function model is determined as a predetermined reference amount of input for control input Uv and as a primary function that passes through a predetermined reference number of revolutions in the reference amount of input, in a coordinate indicating the number N of fan revolutions with respect to an amount Uv of control input to the fan motor 42. On the basis of the actual values of the amount Uv of control input to the fan motor 42, the detected number Nd of revolutions of the fan motor 42, the reference amount of input, and the reference number of revolutions, a learning section 230 learns in sequence the inclination of a primary function model used for feed forward control. |
