<p>A synchronous machine controller capable of generating a torque as close to a desired command torque as possible while considering the limit of the output current of a power converter. The synchronous machine controller comprises a torque current command generator (9) composed of a torque current calculator (15) for calculating a torque current command idelta** from the torque command tau* and the magnetic flux command Phi*, a torque current limit generator (14) for generating a generatable torque current command maximum value idelta*max on the basis of the magnetizing current command igamma* and the current limit value imax, and a limiter (16) for limiting idelta** on the basis of idelta*max, a magnetic flux command generator (10) for calculating a magnetic flux command Phi* on the basis of idelta* from the torque current command generator (9), a magnetic flux calculator (5) for calculating an armature interlinkage magnetic flux feedback value |Phi| on the basis of the armature current feedback value, and a magnetic flux controller (13) for generating a magnetizing current command igamma* so that Phi* agrees with |Phi| and inputting the magnetizing current command igamma* into the torque current command generator (9). ® KIPO & WIPO 2007</p> |
