    摘要： The present invention relates to a method (200) and system (100) for controlling a rotary electric machine wherein a state of the rotary electric machine is determined between a low speed state and a high speed state. In the low speed state, a first rotor position (P1) and a first rotor speed (S1) are estimated based on intra-PWM current ripple (ΔX), a mean current vector (Y) and an inductance vector. A second rotor position (P2) and second rotor speed (S2) is estimated based on average current flowing through stator phase windings. State of rotary electric machine is selected based on estimated first rotor speed (S1) and/or estimated second rotor speed (S2). At low speed state, PWM signals are updated based on estimated first rotor position (P1), and at high speed state, PWM signals are updated based on estimated second rotor position (P2).

    摘要： In an operation area presentation device according to the present invention, a reception unit is configured to receive history data of a position of an operation site in which a work machine is present. A calculation unit is configured to calculate a staying time of the work machine for each of a plurality of areas of the operation site. A generation unit is configured to generate an operation area map obtained by mapping the staying time for each of the plurality of areas to a map of the operation site. An output unit is configured to output the generated operation area map.
