Abstract: A hologram generation method includes a pattern setting step, an intensity image calculation step, and an evaluation value calculation step. In the intensity image calculation step, zero padding is performed on a complex amplitude distribution acquired when a candidate pattern set in the pattern setting step is presented on an input plane, and a candidate intensity image is generated based on a result of a propagation calculation of the complex amplitude distribution after the zero padding. In the evaluation value calculation step, an evaluation value is obtained based on an intensity correlation between the candidate intensity image and a target intensity image. By using an optimization method, while changing the candidate pattern set in the pattern setting step, the respective steps are repeatedly performed, and any one candidate pattern is selected as a hologram to be presented on the input plane based on the evaluation value.

Abstract: A rotating electrical machine control device shifts a control system to synchronous five-pulse control when an operating point crosses a second boundary from a state in which asynchronous pulse-width modulation control is being executed, and shifts the control system to the asynchronous pulse-width modulation control when the operating point crosses a first boundary from a state in which the synchronous five-pulse control is being executed. The first boundary is set such that the number of switching pulses per unit rotational speed by the synchronous five-pulse control immediately before the operating point crosses the first boundary is smaller than the number of the switching pulses per unit rotational speed by the asynchronous pulse-width modulation control immediately after the operating point crosses the first boundary.

Abstract: The magnetic pole position of a rotary electric machine is electrically derived accurately by reducing a voltage error due to a dead time while suppressing the influence on the operation efficiency of the rotary electric machine. A control device performs dead-time compensation, and performs current feedback control in a d-q-axis vector coordinate system using a magnetic pole position computed on the basis of an induced voltage produced by rotation of a rotor or on the basis of a response component to a high-frequency observation signal applied to the rotary electric machine. In the case where the rotary electric machine is controlled by deciding current commands Id*, Iq* in the d-q-axis vector coordinate system, the rotary electric machine control device controls the rotary electric machine such that the magnitude of an armature current Ia becomes equal to or more than a lower-limit current Ia_min prescribed in advance.
