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: A rotating electric machine driving apparatus includes a controller section that obtains an electric current detection value and generates instruction signals for switching ON and OFF of switching elements based on the electric current detection value. The rotating electric machine driving apparatus also includes an IC that is provided with a signal amplifier for outputting amplified signals, which are amplified instruction signals output from the controller section. When an abnormal state, in which one of an instruction signal and an amplified signal amplifying the instruction signal is an ON instruction and the other one of the instruction signal and the amplified signal is an OFF instruction, continues for at least an abnormality determination time, an abnormality detector determines an abnormality of the amplified signal, which realizes an appropriate detection of an abnormality of the amplified signal.

Abstract: An electronic control device includes a plurality of control circuit units, a signal line, and a sneak-in suppression circuit. The plurality of control circuit units are connected to separate grounds, respectively. The signal line connects a first control circuit unit and a second control circuit unit. When a system is defined as a combination of a component and a ground corresponding to a control circuit unit, the sneak-in suppression circuit suppresses a sneak-in of electric power from the ground of one system (i.e., a subject system) to the other system connected by the signal line for preventing a cascading failure.

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.
