摘要： In a motor control apparatus for controlling an AC motor with an inverter, a current estimation value is calculated based on a current detection value of one phase of the motor and a rotation angle of the motor. A difference between a current command value related to driving of the AC motor and the current estimation value is calculated. A first voltage command value used to generate a drive signal related to driving of the inverter is calculated based on the difference. A sign of the difference is reversed at a reverse interval when the rotation speed is not greater than a determination threshold.

摘要： A movement control apparatus includes: an actuator that causes a driven body connected to a driving coil to perform reciprocating movement; a signal generation unit that generates a velocity command signal which indicates a target velocity of the driven body; a driving unit that supplies electric current corresponding to a driving signal to the driving coil; a voltage detection unit that detects induced voltage generated in the driving coil, and outputs a voltage signal corresponding to the induced voltage; a signal correction unit that corrects, based on the driving signal and the voltage signal, the voltage signal to adjust a shift of a resistance value from a reference resistance value of the driving coil, thereby generating a velocity signal; and a control unit that generates the driving signal based on the velocity command signal and the velocity signal, and outputs the driving signal to the driving unit.

摘要： A position-command-pulse generation unit generates a position command pulse to be output to a motor driver by advancing an initial phase thereof by a phase indicated by initial phase information preset in a device. The initial phase information indicates an arbitrary phase in a period of a half cycle of a first pulse of the position command pulse.
