摘要： A control system for a synchronous machine including a converter for converting DC voltage to AC voltage or AC voltage to DC voltage. The synchronous machine is driven by the converter. The control system further includes a magnetic pole position presuming device for performing a presuming operation to presume a magnetic pole position of the synchronous machine based on high-frequency components of a voltage applied to the synchronous machine and a current flowing into the synchronous machine, and a control device for controlling the converter based on the magnetic pole position presumed by the magnetic pole position presuming device. The control device controls the converter so as to contain significant high-frequency components in the voltage or the current used in the presuming operation when a mean voltage or a mean current output from the converter is spatially in a region close to a straight line containing starting and ending points of non-zero voltage vector output from the converter.

摘要： A PWM modulation unit modulates a three-phase voltage instruction, which is input, on the basis of a PWM method, and outputs a gate signal to each phase switching element of an inverter. A high-frequency component arithmetic unit calculates, at each time of switching of the inverter, a high-frequency component of a current occurring due to a voltage which is determined by the PWM modulation unit and is output from the inverter. An index arithmetic unit calculates, as an index R proportional to a rotational phase angle estimation error, from the high-frequency component of the current. A rotational phase angle estimation unit executes an estimation arithmetic operation of the rotational phase angle by using the index R. The invention provides a synchronous motor sensorless control apparatus which enables stable driving with simple adjustment, and does not cause an extreme increase in amount of arithmetic calculations.
