    • In application of a square wave voltage to a motor MG2 to make the motor MG2 output a torque equivalent to a torque command Tm2*, the procedure of square wave control corrects reference phases ψb and −ψb as phases for maximizing an absolute value of the output torque of the motor MG2 with a rotational position detection error θerr and sets the results of the correction to an upper limit phase ψul and a lower limit phase ψll of the square wave voltage (step S110). A target voltage phase ψ* is set within a phase range defined by the upper limit phase ψul and the lower limit phase ψll, in order to reduce a torque difference between the torque command Tm2* and a torque estimate Tm2est (steps S120 and S130). An inverter 42 is controlled based on the target voltage phase ψ* and a rotational angle θ of the motor MG2.

    • A control unit of a rotary electric machine control system includes a stationary switching module and a transitional switching module. The stationary switching module switches over a control mode from a rectangular wave voltage phase control mode to an overmodulation current control mode by using a current phase of a smoothed current produced by filtering of high harmonic components on an actual current in a stationary operation state. The transitional switching module switches the control mode from the rectangular wave voltage phase control mode to the overmodulation current control mode by using the current phase of the actual current in a transitional operation state. The control mode is switched over by comparing the current phase of the actual current with a transitional switching reference line, which is preset separately from a switching reference line used for comparison with a current phase of the smoothed current.
    • 旋转电机控制系统的控制单元包括固定切换模块和过渡切换模块。 固定切换模块通过使用通过在静止操作状态下对实际电流上的高次谐波分量进行滤波产生的平滑电流的电流相位而将控制模式从矩形波电压相位控制模式切换到过调制电流控制模式。 过渡切换模块通过使用过渡操作状态下的实际电流的当前相位将控制模式从矩形波电压相位控制模式切换到过调制电流控制模式。 通过将实际电流的当前相位与与用于与平滑电流的当前相位进行比较的开关基准线分开预设的过渡开关参考线进行比较来切换控制模式。
