步进电动机的角位移量与输入脉冲数严格成正比，电动机转动一圈后，没有累积误差，所以步进电动机是数字控制系统常用的执行电动机，并且广泛的应用在小卫星上。为了 使步进电动机在小卫星上安全运行必需在地面做相应的检测。下面介绍在小卫星有效载荷地面检测仪中利用WindowsXP多媒体定时器实现步进电动机高精度控制的方法。-stepper motor angular displacement volume and input pulses strictly proportional to motor ro

This paper presents the Direct Power Control of Three-Phase Matrix Converters (DPC-MC) operating as Unified Power Flow Controllers (UPFC). Since matrix converters allow direct AC/AC power conversion without intermediate energy storage link, t

在Windows操作系统中，任务栏的右边(托盘)会常驻几个图标，如输入法切换图标、音量控制图标等，本文将详细地介绍用VC设计这种托盘图标程序的方法，给出代码实现。 -In the Windows operating system, the right side of the taskbar (tray) will be resident in several icons, such as input method to switch icons, volume control icons, et
