摘要： A q-axis target current setting unit generates a q-axis current command value based on a steering input signal from a steering torque sensor and a vehicle speed signal from a vehicle speed sensor. An electric motor generates a predetermined torque based on the q-axis current command value and a q-axis current (a torque current) to which a fed back q-axis real current is added. On the other hand, a d-axis correction current setting unit sets a field weakening current (a d-axis current) in response to a voltage saturation (duty ratio=driving voltage of electric motor/power supply voltage) output from a voltage saturation calculating unit. For this reason, when the voltage saturation becomes high, distortion (harmonics component) in current can be decreased by decreasing the voltage saturation while keeping the torque constant using a predetermined torque current, and a torque ripple can be suppressed.

摘要翻译： q轴目标电流设定单元基于来自转向转矩传感器的转向输入信号和来自车速传感器的车速信号生成q轴电流指令值。 电动机基于q轴电流指令值和反馈q轴实际电流相加的q轴电流（转矩电流）产生规定的转矩。 另一方面，d轴校正电流设定单元响应于从电压饱和（占空比=电动机的驱动电压/电源电压）输出的电压饱和来设定弱磁电流（d轴电流） 计算单位。 因此，当电压饱和度变高时，通过使用预定的转矩电流保持转矩恒定，通过降低电压饱和度可以降低电流的失真（谐波分量），并且可以抑制转矩波动。

摘要： A hand-held satellite mobile phone terminal contains an antenna deployment element with a small antenna attached to the tip area of the antenna deployment element The antenna deployment element is usually folded and stored on the rear side surface of the body of the hand-held satellite mobile phone terminal, and is deployed to become vertical to the rear side surface of the hand-held satellite mobile phone terminal body when it is used. The antenna deployment element is attached to the body of the hand-held satellite mobile phone terminal through a rotational axis so that the small antenna attached to the antenna deployment element can be rotated after deployment in order for its plane to become parallel with the ground surface. Also, the hand-held satellite mobile phone terminal is usable both in a satellite communication system and in a terrestrial cellular communication system. For this purpose, the antenna deployment element, batteries and circuits for satellite communication are installed as one package, which can be folded and stored on the rear side surface of the body of the hand-held mobile phone terminal, and which can be removed freely so that it is replaced by another package having the same attachment size as the one package and containing only batteries, when the hand-held mobile phone terminal is used in a terrestrial mobile communication system.
