摘要:
A motor control signal output unit of an electric power steering system includes a feedback gain calculation unit (52), and a feedback control unit executes a feedback control with the use of a proportional gain (Kp) and an integral gain (Ki) that are calculated by the feedback gain calculation unit (52). The feedback gain calculation unit (52) sets the feedback gains to large values (Kp=P0, Ki=I0) when the absolute value of an assist gradient (α) is equal to or smaller than a predetermined value (α0) (|α|≦α0). On the other hand, when the absolute value of the assist gradient (α) exceeds the predetermined value (α0) (|α|>α0), the feedback gain calculation unit (52) sets the feedback gains to small values (Kp=p1, Ki=I1:P1

To provide a receiving device, a receiving method, and a receiving program, which are capable of reducing performance degradation in a case where the spatial correlation of a channel becomes high.A transmission signal candidate search unit searches for a transmission signal in a direction in which reception performance is degraded, in MIMO signal detection. A transmission signal candidate generation unit generates transmission signal candidates while suppressing degradation due to the spatial correlation of a channel. In a decision unit, using the transmission signal candidates generated in the transmission signal candidate generation unit, a maximum likelihood sequence is obtained. The maximum likelihood sequence is obtained as transmission signal candidates where a metric is calculated and the metric becomes a minimum.

An image processing apparatus includes a motion vector calculator and an alignment processing unit. The motion vector calculator calculates motion vector information between a fluorescence image of an observed region based on fluorescence generated from the observed region irradiated with excitation light, and a reflected-light image of the observed region based on reflected light from the observed region. The alignment processing unit corrects misalignment of an object between the fluorescence image and the reflected-light image of the observed region based on the motion vector information.

A current command value computation section 22 is provided with a q-axis current command value correction section 31 and an expected voltage utilization factor computation section 32. The expected voltage utilization factor computation section 32 estimates an expected voltage utilization factor f based on a rotational angular velocity ω of a motor 12, a q-axis current command value Iq*, and a power voltage Vb (the maximum voltage Vmax). The expected voltage utilization factor f is the ratio of required output voltage to the maximum voltage Vmax applicable to a drive circuit 18. Based on the expected voltage utilization factor f, the q-axis current command value correction section 31 corrects the q-axis current command value Iq* such that the corrected expected voltage utilization factor f does not exceed a predetermined value that corresponds to the voltage saturation limit.

Based on information security rules, it is not possible to take out a failure HDD to the exterior of a facility for replacement without erasing data therefrom. According to the present storage sub-system, a slot in which failure has occurred and a slot not registered to a configuration information of a storage sub-system are used to simultaneously perform correction copy to a spare HDD and data erase of the failure HDD in parallel, so as to enable the failure HDD to be brought out to the exterior of the storage facility. Further, time required from when failure has occurred to the HDD to data recovery is shortened, so as to prevent deteriorated redundancy that may be caused by another failure occurring during data recovery and to reduce the risk of data loss.

There is provided a compressor device in which resonance in a circulating channel is reduced so that an increase in noise generated from the compressor device is prevented. The compressor device includes: a plurality of blades rotated about a rotation axis; an air inlet extending along the rotation axis and introducing air to the blades; a circulating channel disposed on a circumference centered on the rotation axis and communicating between the air inlet and the shroud of the blades; and a strut extending radially centered on the rotation axis and dividing the circulating channel. Resonance frequencies determined from circumferential lengths in the circulating channels divided by the strut are higher than a noise frequency determined from the rotational speed of the blades and the number of blades.
