Abstract: In a system for controlling a controlled variable of a rotary machine having plural-phase input terminals of the rotary machine in which plural-phase AC power is applied from an AC power applying module to the input terminals, a command-voltage setting module sets, based on a request value for the controlled variable, plural-phase AC command voltages for the plural-phase AC power as a feedforward manipulated variable. A current obtaining module obtains plural-phase AC currents flowing in the respective plural-phase input terminals of the rotary machine. An amplitude correcting module corrects the amplitude of at least one of the plural-phase AC command voltages based on the magnitudes of the plural-phase AC currents.

Abstract: In a system, a triangular carrier wave is compared in magnitude with first and second two-phase modulated command signals. Based on a result of the comparison, on-off operations of the high- and low-side switching elements of two phases of a three-phase inverter corresponding to the first and second two-phase modulated command signals are performed while the high- and low-side switching elements of the remaining phase of the three-phase inverter is fixed to be on or off. A value of a current flowing through a first or second bus connected between a DC power source and the three-phase inverter is measured when a local peak of the triangular carrier signal occurs while none of the high-side switching elements of all the three-phases are on or none of the low-side switching elements of all the three-phases are on.
