  • Method, apparatus, and computer readable medium based program for simulating an alternate current electric motor using a motor model
    Patent number: 7813904
    Abstract: This is to provide a computing method of motor model, a motor simulation method and a motor simulation apparatus in which high-speed real-time simulation is made feasible while saving computer resources. A motor model is formulated, motor model which uses a motor model of alternate-current motor which virtually includes the inverse matrix of an inductance matrix L(?), which is a predetermined function whose variable is a rotary angle ?, and, in the computation of this motor model, the value, which is obtained by computing a matrix ?(?) which is equal to the inverse matrix of the inductance matrix L(?), is used as the value of the inverse matrix of the inductance matrix L(?).
