Abstract

PURPOSE:To zero securely the magnetization component current by performing a closed loop control so as to zero a difference between magnetization component current command value of an armature current and its actual value. CONSTITUTION:After converting actual values ia, ib, ic of an armature current into ialpha, ibeta through a coordinate converter 529, an actual value i1 of a magnetization component current of the armature current is obtained from conversion further through an alpha.beta/1.2 axis coordinate converter 528, and a process controller 530 is operated so that a difference between said value and a command value i1* will be zero. The closed loop control carried out as above may securely zero the magnetization component current of the armature current in a steady state.
