Abstract: PROBLEM TO BE SOLVED: To accurately judge the out-of-step of a synchronous motor when lightly loaded over a wide operation state. SOLUTION: Expected power that is outputted from a motor is obtained based on the torque command and speed of the synchronous motor. On the other hand, consumption power is detected based on voltage and current being applied to the motor. When a parameter including the deviation or ratio of both of them exceeds a preset threshold, it is judged that out-of-step has occurred. When the deviation between the expected power and the consumption power is to be utilized as parameters, the threshold is set in the relationship with the torque command and the speed. When the ratio of the expected power to the consumption power is to be used as a parameter, the threshold is set in the relationship with the speed, thus accurately judging out-of-step with an extremely light load.

Abstract: PROBLEM TO BE SOLVED: To increase calculation accuracy of an electrical angle and the processing speed in a sensorless control of a synchronous motor. SOLUTION: Using voltages Vd, Vq, currents Id, Iq, inductances Ld, Lq, etc., of a d-axis and a q-axis of a synchronous motor, an electrical angle θis calculated by the following formulae. θ=θ(n-1)+k1.ΔId+k2.Σ(Id); ΔId=Id(n)-Id(n-1)-t(Vd-R.Id(n-1)+ω.Lq.Iq(n-1)/Ld; ω=(k1.ΔId+k2.Σ(ΔId))/t; where (n-1) is the value of each parameter in a former timing, (n) is a value at the present timing, R is the resistance value of a coil, (t) is the execution cycle of an operation, and K1, K2 are factors. By this method, a proper gain is easier to set with good accuracy and the number of operations can be reduced, and therefore the processing speed can be increased.

Abstract: PROBLEM TO BE SOLVED: To improve the voltage utilizing efficiency of a controller of a motor, by performing its voltage control through a rectangular wave when its PWM control has exceeded a limit. SOLUTION: After creating command values Vu*, Vv*, Vw* of the control voltage of a motor (S101), its peak value Vac is calculated (S102). Then, when the peak value Vac is larger than an associated value, the motor is controlled by a rectangular-wave voltage (S104). In this case, the motor is controlled to make the peak value of the fundamental-wave voltage of the rectangular-wave voltage which is obtained by its Fourier inverse-transform coincide with the peak value Vac. Thereby, the shock received by the motor in the transitional time of its control can be reduced.

Abstract: PROBLEM TO BE SOLVED: To detect an electrical angle with accuracy and ideally control the angle by impressing a pulse voltage having an arbitrary time interval upon multiphase coils and detecting the variation of the currents flowing to the coils. SOLUTION: A pulse voltage having an arbitrary time interval is impressed upon the multiphase coils U, V, and W of a motor-driven rotary machine 60 and the variation of the currents flowing to the coils U, V, and W caused by the impressed voltage is detected. Thus the detected electrical angle between the rotator and stator of the machine 60 is measured. Namely, the driving condition of the machine 60 is detected in advance and the relative timing after the impression of the pulse voltage is started is decided to a prescribed timing in the pulse voltage impressing duration as the detecting timing of the variation of the currents flowing to the coils U, V, and W in accordance with the driving condition of the machine 60. At the decided detecting timing, current detectors 12 and 14 detect the variation of the currents flowing to the coils U, V, and W and an electrical angle detecting section 40 decides the electrical angle based on the detected variation. In addition, a control section 20 controls the machine 60 based on the electrical angle.

Abstract: PROBLEM TO BE SOLVED: To shorten switching time when switching from an overdrive coupling to an underdrive coupling. SOLUTION: A control unit gives a switching command from an overdrive coupling to an underdrive coupling (S202). By this command, an actuator of a switching device is immediately started (S204). The control unit controls the actuator and separates a rotor shaft of an assist motor from a crankshaft of an engine (S206). The control unit controls the assist motor, accelerates rotation of the assist motor, increases the number of rotation of the rotor shaft of the assist motor and numbers of rotation are synchronized so that the number of rotation of the rotor shaft may be conformed to the number of rotation of an outer rotor shaft to be a drive shaft (S208). The control unit controls the actuator when the number of rotation of the rotor shaft coincides with the number of rotation of the outer rotor shaft and couples the rotor shaft with the outer rotor shaft (S212).
