Claim 1:
2. The rotating electrical machine control system according to claim 1, wherein
the inverter control device performs feedback control of the rotating electrical machine in a d-q-axis orthogonal vector coordinate system, based on deviation between current instructions obtained based on target torque of the rotating electrical machine and the actual currents, the d-q-axis orthogonal vector coordinate system having a d-axis indicating a direction of a magnetic flux of permanent magnets provided in a rotor of the rotating electrical machine and a q-axis orthogonal to the d-axis, and
the inverter control device
transforms the actual currents into two-phase currents in the d-q-axis orthogonal vector coordinate system, the actual currents being alternating currents of N phases,
computes two-phase voltage instructions in the d-q-axis orthogonal vector coordinate system, based on deviation between two-phase current instructions and the two-phase currents, the two-phase current instructions being the current instructions in the d-q-axis orthogonal vector coordinate system,
transforms the two-phase voltage instructions into N-phase voltage instructions to be applied to the coil sets of N phases, and
generates the switching control signals based on the N-phase voltage instructions.
