摘要： In a controlling device (100) for a permanent magnet synchronous motor, an asynchronous pulse mode is switched to a synchronous pulse mode in a situation where a modulation factor has become equal to or larger than a first set value or in a situation where an inverter (2) output frequency has become equal to or higher than a second set value. The synchronous pulse mode is switched to the asynchronous pulse mode in a situation where the modulation factor has become smaller than the first set value, and also, the inverter (2) output frequency has become lower than the second set value. By setting the second set value so that the number of pulses included in a half cycle of an output voltage fundamental wave of the inverter (2) is equal to or larger than a predetermined value, it is possible to inhibit current oscillations and torque ripples from occurring in the motor.

摘要： To avoid control failure resulting from startup of a PMSM that is windmilling, initial speed and position are determined before startup. A controller uses a FOC routine having a speed PI control loop, field-weaken control, a current PI control loop, and a speed observer. When the controller receives an instruction to start the PMSM, it delays startup and executes an “estimation” stage, in which the controller executes the FOC routine but with the speed PI control loop and the field-weaken control disabled. The estimation stage is repeated multiple times, with estimates converging to actual speed and position through successive iterations. When estimated speed and position values have stabilized, the motor is started using the estimates as initial speed and position for driving the PMSM. The FOC routine, with the speed PI control loop and the field-weaken control enabled, is used to drive the PMSM.

摘要： In an electric power steering system, a control signal output section outputs independent dual-system control signals to driver circuits that are disposed in connection with independent dual-system motor coils. The control signal output section gives high priority to the output of the control signal to the other system, when the occurrence of energization failure is detected in one system. When the energization failure occurring phase is only one phase and the value of the basic command exceeds the upper limit of the priority command, the control signal output section outputs the control signal to the driver circuit in the system where the energization failure has occurred in order to supply electric power in which the two phases other than the energization failure occurring phase are used as the energized phases on the bases of the complementary command that corresponds to the excess of the upper limit.

摘要： Methods, system and apparatus are provided for reducing power loss in an electric motor drive system that includes an electric machine and an inverter module. A controller determines whether a torque command (Tcmd) is less than a minimum torque threshold (Tmin) that is required to disable the inverter module, and if so, increments a counter and determines whether the torque command (Tcmd) remains less than the minimum torque threshold (Tmin). When the torque command (Tcmd) remains less than the minimum torque threshold (Tmin), the controller checks to determine whether a current count value (n) maintained at the counter is greater than a count threshold (nth), and if so, the controller can generate a disable signal to disable switching within the inverter module.

摘要： An overmodulation PWM control unit includes a voltage amplitude calculating unit for calculating a voltage command amplitude of an original voltage command based on current feedback control, a voltage amplitude correcting unit for performing linear compensation on the voltage command amplitude so that a fundamental amplitude of a pulse width modulation voltage provided from an inverter may match the original voltage command amplitude, and a harmonic determining unit for determining presence or absence of superimposition of a three-order harmonic component on a phase voltage command. The harmonic determining unit performs switching between presence and absence of the three-order harmonic component based on transition of the original voltage command amplitude to avoid passing through a change point where discontinuity occurs in the voltage amplitude characteristics representing a relationship between a fundamental amplitude obtained in advance for each of the cases of presence and absence of the superimposition of the three-order harmonic component and the voltage command amplitude required for achieving the fundamental amplitude.
